I though about that myself, something like:

	x = $(f(3)+4*5)

so that part inside the $(...) is executed  by the lexer
and the result, a lua object, is passed up to the parser
as a special kind of constant.

But I never started to implement it.  It was just an idea...

I made a complete lua with integer arithmetic.  No floating point
anywhere.  The standard lua has some problem when LUA_NUM_TYPE is
long - it still uses floating point in a lot of places.

I once posted a patch for this to the mailing list.  In the
meantime I've added some more stuff (more operators, and, or, xor,
not, shift left/right, ...).
