[Sc-devel] [approve] asBoolean

So many times I've come across the choice to either use a true/false pair (i.e. I have to check if nil separately) or use the formula if(x != true) ... (i.e. have no true inversion: (x == false) means something else than (x != true).not.

my suggestion: asBoolean

Object:asBoolean { ^true } // or false?
Nil:asBoolean { ^false }
Boolean:asBoolean { ^this }

then we write:

if(x.asBoolean) { ... }
