Have updated PHPPyu, mostly just code optimizations.
Like a writer, always editing with each new draft, I find myself always seeking ways to optimize the code. Most code I write is done in that manner. I usually do a "first draft" just to prove a concept, without worry about how the code looks. Once I have something working I re-write it, all the while thinking of re-use and of future maintenance. Sometimes I do multiple drafts before I feel the code is "right."
It works for me.
