Micro-Optimisation decreasing initial parsing time by 10%
python () {} and python __anonymous () {} are as the same
says functions without a name. They get executed when the
main bb file is completely parsed. This is used to set
information like FILESDIR.
This is a python method so it gets evaled which means compiled
and executed a lot of times. By moving the code of the anonfunc
into a proper method this is only compiled once. The result is
is the 10% speed up when parsing.
Reindent anonfuncs and new defs without tabs and four spaces
