Don't use prototypes. They were design for other things than what you
want to do. 99.9% of everything you are likely to do does not need them.
To pass a reference of a subroutine to another:
foo( \&other_sub, $text );
To pass an anonymous subroutine:
foo( sub { print "in anonymous sub\n"; }, $text );
To save them in a variable:
my $other = \&other_sub;
my $anony = sub { print "in anonymous sub\n"; };
