I'm not a big fan of the foreach syntax.  It's so easy to forget 
or accidentally add parentheses while coding, or read it wrongly 
while skimming over the code.

Not sure if anything can be done against that, though.  Maybe add 
an alternate "for (.. in ..)" syntax that doesn't have that 
problem?
