in reply to Accessing Subroutine Arguments

In my progress as a perl programmer, I started out with your first method, passing in a list of variables, and then grabbing them in that order in the subroutine.

As it got more advanced, I started using the second, (usually with a hash reference or something similar like you posted).

Then in some cases, where I keep passing the same value, since it does not change much, I found creating an object, blessing it, and making methods to do the work was a little easier to do.

[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.
[marioroy]: I was unable to run parallel with Win32::Console. Fortunately, running parallel behind Win32::API is possible.
