If "fruit on toast" is a "frivolous luxury", then I can't think of a better example of how unimaginable wealth inequality in this country has become.
Even at $8, that's on par with a pint of beer at a bar in SF.
What a life of frivolous luxury.
No. If it were, I wouldn't even consider using it.
Switching between multiple interpreter installations is pretty easy (a drop down in a preference pane) -- it will find every interpreter on your path, and can index anything defined in $PERL5LIB for auto-complete goodness.
The debugger is great -- I love being able to set conditional breakpoints using a possibly complex expression in the native language (not just simple var=val type things).
Ever heard of Komodo? I've been using it for years for Perl development, plus it supports Python, Ruby, and a host of other languages.
I wouldn't consider doing any serious Perl dev without it.
As for named parameters, the clean/simple style I like to use is:
do_stuff(Foo => 1, Bar => $baz);
sub do_stuff {
my %args = @_;
my $foo = $args{Foo};
# etc...
}
