Description[edit]

This is a doc attached to my sandbox. I'll use it to see the effects of my changes W/o messing something important

NOTE: LUA is usually slower than ParserFunctions for short statements. The factor varies from 7-1 to 2-1.
Lua only is an advantage to long statements, nested logic, loops (maybe others case i don't see right now).

expr only uses 1 Preprocessor visited node count, in general. Variables may change that.
