case sensitivity?

Will Pez continue to use case-insensitive words?

Nope. Per the TODO, all of those calls to ucase() are going away, the primitives are going to be lower-cased, and we'll be case-sensitive.

Incidentally, the performance hit from the capitalize-everything approach (I guess strcasecmp() wasn't around for some of the previously supported platforms?) comes in interpret mode and during compilation; it's all addresses for compiled words, so no major hit there.
