This is called a soft reference, and soft references are generally a bad
idea. However, it should work.
I would suggest using a hash, where the keys of the has are $sub as above,
and the values subroutine references. The code would then look something
like this:
my %subs = (
foo => sub { print "foo" },
bar => \&bar,
);
foreach my $sub (@list_of_subs) {
&$sub; # or $sub->(... arguments ...)
}
This is safer if @list_of_subs is coming from user input. It's also easier
to verify; to determine if $sub is valid, simply check %subs for the key.
