Valid points both, perhaps I should do a benchmark and see which of our methods is faster. It was my goal to decrease the number of or's in the production, but perhaps regex's aren't the way to go. As for the nature of the first line, I wanted to be sure that no one ever wrote =>= to simplify later processing, though looking at it now I don't think it would make much of a difference, but it does allow me to specify what the error was.

As for the comments, this is part of a school project, and while the comments do need to be cleaned up, they will help me to explain in a hurry the purpose of each elment to the person reviewing it.

I'll look into those benchmarks and, if I remember, post them here soon... too much to do, too little time...

My code doesn't have bugs, it just develops random features.
