"It works by keeping track of any lexically enclosing statement that is 
looking for an else clause, so if an else clause is found for the current 
statement without a following { }, then it is marked as illegal."

Can someone explain that for me? (My brain is completely scrambled right now 
from a nasty Flash/IE bug.)

This is a great idea. I'm used to use tools like checkstyle in java (or 
some others depending on the language) that trigger an error if an if 
statement without brace contain any conditionnal (if, for, while, . . .) 
or as an else. It makes the code myuch more clearer and avoid stupid 
mistake that sometime are hard to discover.

Including this at the parser level is a great idea. The D's solution is 
softer than mine, but this is a good thing. At parser level, you should 
only limit what is error prone, not ensure coding quality standards that 
can vary from a devellopper to another.

Good job.
