Please do not do this, please... 
Recently I was working with a modules written by a programmer, 
who used "_" instead of "self". 
This was so "not in line" with the rest of the system, 
that it took me extra hour or two to get accustomed 
and switch back and force (self in "standard" modules and _ in "economical").
