If that is all you have, it is pretty much useless.  "(a + b + c) = d"
becomes a confusing way to write "d = (a + b + c)".

It is no work, because you are not adding anything useful.

In Metapost (and Metafont), you have a /declarative/ language, not an
imperative one (like C and CAlive).  So you can write:

	a + b = 3;
	12 = 2 * a - b;

and the language will conclude that a == 5 and b == 2.  That is a very
powerful feature.  If you can figure out how to integrate something like
that into your language in a practical and natural way, /then/ you would
be onto something new.  It may be possible to use such declarations for
optimisation hints, or for static or run-time checking.
