Calling keys() (or values()) in void context is quite efficient.
Whether or not you appreciate the aesthetics is perhaps quite another

bout the solution in
the docs for each.
There is a single iterator for each hash, shared by all "each",
"keys", and "values" function calls in the program; it can be reset
by reading all the elements from the hash, or by evaluating "keys
HASH" or "values HASH".
perldoc -f each

Probably. Either provide a forward declaration of th
is a parse_from_filehandle()
method which seems to be what you are after. Alternatively, you can
download podlators-1.07 and PodParser-1.18 from CPAN. I don't think
either has a requirement for 5.6.0.
