In Iterate.pm, I prototype an iterator
subroutine for each type of variable
that I want to iterate.
sub IterArray(\@&){}
sub IterHash (\%&){}
How would I create a single subroutine name,
like "Iterate", that would be overloaded to
call the IterArray or IterHash sub depending
on the type of variable used in the call?
Iterate @arr sub { print "value is ".($_[0])."\n"; }
Iterate %hash sub { print "key is ".($_[0])."\n"; }
Or could there be ambiguities on some data types
where stating the data type explicitely in the subname
would more likely guarantee the expected behaviour?
This is more of a coding style question.
