Re: How to convert a symbolic reference to a hard reference

I see your question has been answered directly by a few other fine Monks, but I thought I might add something. If you'd like to get a coderef without using eval, you can use can. For example:

sub foo {
  print "Foo!\n";
}

my $pkg = "main";
my $sub = "foo";

my $cr = $pkg->can($sub)
  or die "Can't find '$sub' in package '$pkg'\n";

$cr->();

Very nice, thanks. You don't even have to split the package off: `$sub = "X::foo"; $cr = main::->can($sub);` [download] You can just use any existing package name. (I say `main::` instead of `main->` in case there is a &main sub.) If you are downvoting this for other than lack of interest, thanks for sending me a message or reply to let me know why so I can do better (or just stay quiet) next time.	[reply] [d/l] [select]
