I don't have a problem with the semicolon either.  Anyone not using /free 
mainly because of the semicolon is being petty.  And cutting their nose 
off to spite their face.

I don't have a problem with the semicolon.  Granted, it's not consistent
with other languages and yes I do forget one here and there, but I don't 
see
it as a big deal.

I think you have a very valid point on the multiple chain syntaxes.
