hmm... I actually sort of like that ... statement: statement: statement: suite is equivalent to statement: statement: statement: suite On its own, it is a pure win to say "This statement really only does one thing; it is the subordinate statement that has a suite".

Sure, just like short-circuited logical expressions. However, it is unambiguously expressed.
and it also becomes something of a problem to parse mentally.
Agreed (and Greg at least agrees, too).
