I'm in favour of the feature and "a := b".

I almost think I would purposely use it everywhere, for two reasons:

  1) consistency between different contexts

  2) because it has always irritated me that programming languages use 
"==" to mean what mathematicians call "=" and "=" to mean something that 
mathematicians rarely do.
