I'm playing around with associative arrays right now and I can't
seem to figure out how to add additional objects to the array. I
tried insert but it doesn't recognize both arguments.
Also, if I do this it produces an error:
Node[bool] test;
Node node;
Node[bool] temp = [ false:node ];
test
Ok, thanks for the help, much appreciated.

I'm still messing around with binary heaps. I've successfully
created and used it on the function level but for some reason
when I move it to the class level I get an error. Furthermore,
i'm not entirely sure how to use a binary heap without auto as
the type.

Thanks! This clears up that part very well. I'm a lot closer to
having a decent path finding algorithm now.

Ah, thank you. I didn't realize taht SList is a struct and that
it used value semantics. That clears this up.

Right now i'm struggling with trying to understand how to remove
