This is a small optimization of pp_pow.
The following:
use Benchmark;
timethis(3, 'my $x;
for my $base (-8 .. 8) {
for my $power (0 .. 10) {
$x = $base ** $power;
$x = $base ** $power;
$x = $base ** $power;
$x = $base **

With your patch, I get :
$ ./perl -e 'print - x undef'
Segmentation fault
The problem coming from the line :
count = SvIVX(sv);
when sv is PL_sv_undef.
Moreover you shouldn't be setting count = IV_MAX in all cases, I think.
So, not applied as is.
I'm just a beginner, so I don't know
Due to recent codes changes (cleanup, variable declaration moved) in this
part, your patch doesn't apply cleanly. Can you resubmit one against a
more recent bleadperl ?
No problem.

Here are some cosmetic changes of perlfunc:
1. Documented no-operand versions of chdir, eval, exit, gmtime.
2. Normalized Cfoo() to foo().
3. Normalized $foo to C$foo.
4. Changed =item import to =item import (LIST).

Didn't we conclude it would be better to give Pod::Html the same foo()

ActivePerl HTMLs have links to functions even where there are no

I see three problems with this function:
1. [#36674] -undef results in -0.0 rather than the expected 0.
This is probably easy to fix, but I don't know if undef is the only value for

Anyone else for putting all the documentation on some kind of heavily

I was going to write that we need a PodWiki, but it appears that this thing
already exists!
So I think this is a great idea. At least we should give it a try.

The following program invokes beta once instead of twice.
Extremely non-intuitive.
Really? It is effectively:
$c = beta ($a) if ( ! defined $c ); # the if condition is true
$c = beta ($a) if ( ! defined $c ); # the if condition is false
1) seems like it shouldn\'t compile.
Why not?
2) $c is
