Hi all,
I have a hash of hashes and arrays. I'm able to print the all the keys
of the outer hash, and print the embedded hashes and arrays
individually, now I want to print the entire contents of the outer
(matrix) hash.
I need something like:
for each key in the outer hash
{ if (the key is a reference to a hash)
{ print the contents of the hash;
}
elsif (the key is a reference to an array)
{ print the contents of the array;
}
}
I have everything in place, but don't know how to tell whether I'm
looking at a hash or an array.
Any hints?
P.S. In linguistics, we call the embedded sentences "embedded
sentences," clever, I know, and those into which they are embedded
"matrix sentences." What is the parlance in Perl/formal languages?
