Perl Programming

This is where perl starts to break down! To loose a bit of steam.
When you start pointing to data structures, you need to keep track of who's pointing to them, because you don't want to get rid of it while other pointers are pointing to it.

A hash just contains a scalar .

Wait a sec, I used this for assignment 1!

It's more efficient to pass a reference for the same reasons that it is better to do it in C.

Wasteful and dangerous to create a temporary handle, so like NEW in C, you can create a new instance of something and get a handle back on it.

I think I'm getting this stuff. Conceptually it makes sense. It's beautiful in its simplicity actually.

Programming is simple. That's my new mantra.

So now we can create higher dimension data structures! Hooray!

I like perl. The debugger warnings are friendly too.

You can use a hash to effectively emulate C structs.
