in reply to general hash questions

That should work fine. Put your hash def in a file "" and then in your script file have the line
require "";
(This assumes that and your script are in the current directory in which you are running the script.)
If the hash def is in a file "", then you can have the line use filename; (This latter assumes that is in the same directory as the script using it and that you are running the script in that directory and that the current directory is included in @INC.)
But read the docs on "use", "require" and also "do"; the latter may be more appropriate for what you want (and easier to manage.)
Oh, and there shouldn't be a limit on the size of the hash - till you run out of memory.
(Update: Looks like the problem was solved while I was responding.)

[marioroy]: choroba++, Discipulus++. It depends on the type of module. Data-type "only" modules are likely multi-process safe, re: Hash::Ordered, Tie::IxHash.
[marioroy]: ... when shared via MCE::Share-> share(...)
[marioroy]: Net type modules are likely not multi-process safe unless stated in the documentation.
[marioroy]: The Prima author fixed his module to be both thread and multi-process safe. Thanks Dmitry.
[marioroy]: Of all the GUI-type modules, Prima was the worst regarding thread/multi- process safety. Now, it's the best for safety. ;-)
[marioroy]: Tk, Gtk2, Gtk3 requires extra care.
