You should know better than to try this. Csh is intrinsicly broken.
Anyway, it's not a bug, it's a feature. It's documented:

	The foreach, switch, and while statements, as well as the
	if-then-else form of the if statement require that the major
	keywords appear in a single simple command on an input line
	as shown below.

Sun says it better:

	Each occurrence of a foreach, switch, while,  if...then  and
	else built-in must appear as the first word on its own input line.

BTW, don't try piping to them or I/O redirection either.

Another broken feature: for integer values of X & Y try:

	(repeat X repeat Y echo foo) | wc -l

What is printed is not X*Y, but rather X+Y-1.

No one cares enuf to fix csh.
