BTW, some of those details of the syntax of regexps are really
undesirable. Would it be possible for xr to flag them somehow to try
and discourage their use?
Of course, even better would be to flag such uses not only in xr but
more generally. I'm thinking for example of a regexp that starts with
a postfix operator or that backslash-escapes a non-special character.
