Hans is right: this is the kind of grammar transformation you ought to
do if you were using a dumb tool.  But do not do that: you are going
to make your grammar much more complex, harder to maintain, and you
will even loose performances.

Just as nobody would ever program a expr/term/factor grammar for
arithmetics in LR, you should avoid the solution above.
