Right. There are some corner cases though, for example
A*-5
which you'd probably rather weren't interpreted as a single operator
"*-". I believe the hack we use for this involves parsing a trailing
"+" or "-" as a separate operator if the earlier part of the operator
name contains only a certain set of characters. The grotty details
are in the manual ...
