I'm trying to improve on sandfly's code by eliminating the need for temp variables, but getting into trouble. Why does the following code produce
"Use of uninitialized value in subroutine entry at -e line 1.
Undefined subroutine &main:: called at -e line 1." 
my %h=(   HELP => sub {print qq(help\n)},
                  Q=>$h{HELP},
                SAVE=>sub{print qq(save\n)} ); 
print $h{Q}();

I have also tried it by separating the declaration and population of %h, to no avail.
