Your best bet is a dispatch table, which is a hash where the keys are the names of the subroutines you want to execute and the values are the subroutine references (in perl at least) e.g

sub foo { print "in foo\n" }

my %dispatch = (
  foo => \&foo,
  bar => sub { print "in bar\n" },
);

my @data = qw/ foo bar /;

$dispatch{$_}->() for @data;

__output__

in foo
in bar

Or if you're feeling particularly devilish you can just abuse the lack of checking for strictures when creating subroutine references e.g

sub foo { print "in foo\n" }

(\&{"foo"})->();

__output__

in foo

Ok, so you probably wouldn't want to do it like that, but it's always an option ;)
