Agreed, this is better than `^'.

Don't forget that infix dot has the problem that you *mustn't* put
whitespace between the dot and whatever comes next, or it'll be
tokenized as the end of the clause.  This could be very surprising to
those used to putting whitespace around their dots.

Of course, the same is true of dot as a module separator.

Aside from that, I agree, dot would make a better field separator than
module separator.  But `@' isn't too bad.
