#162 — Why is the operand of alignof restricted to a type?

This question came up on c.s.c, so I though I'd ask here.

 From 6.5.3.4 sizeof may be applied to an expression or the
parenthesised name of a type while alignof may only be applied to the
parenthesised name of a type.

Is there a reason for the discrepancy?

#167

This _is_ c.s.c, right?

[Moderator's note: "c.s.c" is somewhat ambiguous, either comp.std.c or 
comp.std.c++. This group is comp.std.c++. See the note below.  - sdc ]
