Any way to enumerate CORE::GLOBAL members?

foolishmortal has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks,

Is there any way to get perl to spit out the names of all builtin functions/vars?

I am thinking of something along these lines (which doesn't yield anything):

for my $func (keys %main::CORE::GLOBAL::) {
    say $func;
}

Thanks for any insight you can provide.

No. For starters, they aren't functions. They are operators. There's no difference between "`print`" and "`+`" except in the arguments they take and the operation they perform. As for variables, it depends on what you mean by special. If you mean those in perlvar, they are in perlvar.	[reply] [d/l] [select]

I couldn't find an easy way using CORE::GLOBAL, but here is an easy way to get perl to spit out functions. Using Pod::Functions, enter this on the command line for example ( macosx ): `perl /sw/lib/perl5-core/5.8.8/Pod/Functions.pm` [download]	[reply] [d/l]

A convenient listing of all builtins/keywords can be found in B::Keywords. In your case, you'll probably want `@B::Keywords::Functions`. blokhead	[reply]
