How to expertly fold perl or other scripting code.

[Harry Putnam]

I see too much output on google that looks very complex when I try to
delve into folding code in emacs.

Is it horribly complicated?

I know some windows editors or ide's do such folding very
quickly... but I'm not going to do my coding on windows.  I'm far to
comfortable on linux or opensolaris, but I would really like to have
the ability to fold/unfold code as needed, quickly and easily.
