Hi
Howdy.
Scouring the books to try and find this, but it's evading me.
How can I test whether something is an array.
For some definition of "something" that includes references, use ref(). :)
ie I have a hash and some values are anon arrays and some are strings. I want to test to see whether one is an array and then traverse it.
if ( ref($some_hash{might_be_array_ref}) eq 'ARRAY' ) { # ... }
Hope that helps.
