+1.  Not only better, but appropriate.

It should be a warning, because it is not an
invalid regexp.

It might generally be a useless regexp, and
it's most likely not what the user intended,
but it's not invalid.

Raising an error would, well, be an error, IMHO.
Displaying a warning during byte-compilation
would be very helpful.
