I think what Ivan meant is that the normal Python rule is that if you 
have a full-colon (ANYWHERE), and you put something after it on the 
same line, then you're done the block. This behaviour is the same for 
method definitions, IF-blocks, the FOR statement, class definitions, 
etc.

However, your change would be an exception to the rule, in that it 
would change what a full-colon is allowed to do, but only in one place.
