You are very close. The trick to remember is that hashes
and arrays can only store scalars. Perl can have complex
data structures only because a reference is a scalar.
in reply to References for subroutines to Hashes in Hashes :)
This means that your hash of hashes is really a hash of
references to hashes. To pass the reference to
a subroutine, then, you need only access the value.
In this case simple remove the preceding slash ( sorry, I
would try to use a code tag, but I am using Opera and it
makes a real mess of things ).
