The only rules are that hash keys are converted to strings, they are unique
and they are immutable (unless you are using a tied hash that changes that
behaviour.) Other than that there are no preset limits on Perl's data.

DESCRIPTION
Variable names
Perl has three built-in data types: scalars, arrays of scalars, and
associative arrays of scalars, known as "hashes". A scalar is a single
string (of any size, limited only by the available memory), number, or
a reference to something (which will be discussed in perlref). Normal
arrays are ordered lists of scalars indexed by number, starting with 0.
Hashes are unordered collections of scalar values indexed by their
associated string key.
