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
