Seems like a good idea to me.  (Put down that torch!  Not for C, but for
another language.)  After all, Pascal manages without the parens around the
expr's in "if", "while", and "case" (Pascal analog of "switch").  Of
course, some Pascalers are amazed that C doesn't have "then" to go with
"if".
(It's a little trickier to get rid of BOTH the parens around the expr in
the "if" AND the "then" keyword - but it's possible.  Look at the way Icon
handles comparable situations.)
