His point was that after typing ':' he will usually put a space. I don't 
really understand this argument, as I know of people that will complain 
when spaces aren't put around ' = '.

I do like the idea of name the arguments in the call for readability. I 
don't think it should be mandatory, nor do I believe anyone has suggested 
that.
