Hi all,
one construct that keeps infuriating me in Perl 5 is when I’m
spelling out an explicit list where I want to include particular
elements only under certain circumstances, ie.
$foo, $bar, $baz, $quux
but $baz should only be part of the list when $wibble is true.
In Perl 5, I can express this using one of two ways: the Looks
Like Java way and the Looks Like Linenoise way.
my @list = ( $foo, $bar );
push @list, $baz if $wibble;
push @list, $quux;
@list
# or
$foo, $bar, ( $wibble ? $baz : () ), $quux
There are other ways too, but all of them are either worse or
colossally worse.
Is there a construct in Perl 6 to express this more immediately?
Something along the lines of the following would seem ideal:
$foo, $bar, ( $baz if $wibble ), $quux
Regards,
