snip
I *wish* it was 5.10 as that has some
very nice features that I am excited about.
like what for example ?
snip
Here are some of the things that are coming in Perl 5.10.
* a switch statement:
given($string) {
when (/^abc/) { $abc = 1; }
when (/^def/) { $def = 1; }
when (/^xyz/) { $xyz = 1; }
default { $nothing = 1; }
}
* The // and err operators (like || and or, but tests for defined
rather than truth)
my $sleep = shift // 10; #does not overwrite 0 like (shift || 10) would
* alternations in regexes are significantly more efficient due to the
use of tries
* recursive regexes
It is now possible to write recursive patterns without using the
(??{}) construct. This new way is more efficient, and in many
cases easier to read.
Each capturing parenthesis can now be treated as an independent
pattern that can be entered by using the (?PARNO) syntax (PARNO
standing for parenthesis number). For example, the following pat‐
tern will match nested balanced angle brackets:
/
^ # start of line
( # start capture buffer 1
# match an opening angle bracket
(?: # match one of:
(? # don't backtrack over the inside of
this group
[^]+ # one or more non angle brackets
) # end non backtracking group
| # ... or ...
(?1)# recurse to bracket 1 and try it aga
in
)* # 0 or more times.
# match a closing angle bracket
) # end capture buffer one
$ # end of line
/x
* named regex captures
It is now possible to name capturing parenthesis in a pattern and
refer to the captured contents by name. The naming syntax is
(?NAME). It's possible to backreference to a named buffer
with the \kNAME syntax. In code, the new magical hashes %+
and %- can be used to access the contents of the capture buffers.
* relative backreferences
A new syntax \g{N} or \gN where N is a decimal integer allows
a safer form of back-reference notation as well as allowing rela‐
tive backreferences. This should make it easier to generate and
embed patterns that contain backreferences. See Capture buffers
in perlre. (Yves Orton)
* \K escape
The functionality of Jeff Pinyan's module Regexp::Keep has been
added to the core. You can now use in regular expressions the spe‐
cial escape \K as a way to do something like floating length pos‐
itive lookbehind. It is also useful in substitutions like:
s/(foo)bar/$1/g
that can now be converted to
s/foo\Kbar//g
which is much more efficient. (Yves Orton)
* UNITCHECK blocks
UNITCHECK, a new special code block has been introduced, in addition
to BEGIN, CHECK, INIT and END.
CHECK and INIT blocks, while useful for some specialized purposes,
are always executed at the transition between the compilation and the
execution of the main program, and thus are useless whenever code is
loaded at runtime. On the other hand, UNITCHECK blocks are executed
just after the unit which defined them has been compiled. See perlmod
for more information. (Alex Gough)
* the smart match operator (~~)
The behaviour of a smart match depends on what type of thing its
arguments are. It is always commutative, i.e. $a ~~ $b behaves the
same as $b ~~ $a. The behaviour is determined by the following table:
the first row that applies, in either order, determines the match
behaviour.
$a $bType of Match ImpliedMatching Code
== = ==
(overloading trumps everything)
Code[+] Code[+] referential equality $a == $b
Any Code[+] scalar sub truth $b-($a)
HashHash hash keys identical [sort keys %$a]~~[sort key
s %$b]
HashArray hash value slice truth grep $_, @[EMAIL
PROTECTED]
HashRegex hash key grepgrep /$b/, keys %$a
HashAny hash entry existence exists $a-{$b}

Another more practical reason is that not everyone has high-speed internet, and having a GB- sized software update would not be a nice user experience for a modem user (though admittedly, some of the past software updates were pretty hefty). So software updates are restricted to keep the size down. Because most users do not use the command-line or develop software, updates to command-line programs never make the cut (developer software has it own update channel). Ed

*ahem* Go back and read Mr Moy'ss email address. He may be in a position to answer this question definitively. :-) FWIW, I didn't see Ed saying that it had been 5.8.8 in _10.4_ for quite a while. (His mode of expression was, admittedly, a bit ambiguous.) But, unless, 10.4 is tracking a different version between uNTEL and PPC, my system perl is 5.8.6 with all the current 10.4 updates installed.
