Recent language features seem to be suffereing from excessive
parenthesisitis.  I worry that people will stop remembering which
expressions requirement parens in which context.  Perhaps the solution
is to require parens around all expressions, a simple consistent rule.
 If so, then adding parens around all statements is a fairly natural
extension, which solves a number of problems like how to make a richer
