you can also build anonymous functions right into the table, if that
helps you maintain them more easily.
%funcs = (
this => sub {
# code for "this"
},
that => sub {
# code for "that"
},
foo => sub {
# code for "foo"
},
bar => sub {
# code for "bar"
},
);
my $key = &somethingThatAssignsTheLookupKey();
$func{$key}->(@funcArgs);
