Comprehensions are expressions and therefore need everything packed into 
them that is needed.

For statements and if statement are statements and both can be followed 
in there suite with an many statements as needed, so there is no *need* 
to pack more than is necessary into the header line. Even doc strings, 
which are conceptually part of the header, were put down into the suite.
