Well, not the syntax checker; that'd be done by the semantics checker.

But I'm not certain whether it should; the comparison operator for byte
strings can compare byte strings with unequal lengths - strings with
unequal lengths aren't equal, and shorter strings are less than longer
strings.

So I guess the idea is that you should be able to compare unequal-length
byte strings; the question is whether comparisons that will *always*
fail should get errors when the expression is compiled.  I'd be
inclined to say "yes" - Gilbert?  Ed?  Anybody else?

Or, rather, the routine that the "Match->Selected" code calls needs to
do that; I've checked in a change to do that.
