Currently, the production `a+ +b` requires a space to disambiguate it from the
increment operator. However, `a++b` is not itself valid, as the postfix
increment cannot be immediately followed by a bare identifier on the same line,
nor can a prefix operator be preceded by one on the same line. Could the
grammar be amended to include this production and make it evaluate equivalently
to `a+ +b`

Maybe it could, but the extra complexity really doesn't seem worth it,
particularly since you'd need the unusual line terminator restriction to avoid
breaking existing code. Other uses of + don't have line terminator
restrictions.
