Yes, there are ways of fooling strict. It's simpler and clearer to just turn it off in the code in question. `my $func_name = 'f'; my $cr = do { no strict 'refs'; \&$func_name }; say $cr->();` [download]	[reply] [d/l]

You can use `can` to return a coderef: `use strict; use warnings; my $doFoo = main->can ('foo'); print $doFoo ? $doFoo->() : "Can't foo\n"; sub foo { return 1; }` [download] Prints: `1` [download] True laziness is hard work	[reply] [d/l] [select]

`can` searches the inheritance tree. It should be used for methods, not functions.	[reply] [d/l]

And yet can works, and as there is no @main::ISA, and you shouldn't pollute UNIVERSAL, `main->can( $foo )` is perfectly legit	[reply] [d/l]
