Subject: Compile time constant folding?

Here's a quick question, now that parrot's close to getting object 
support and the cardinal folks are on their way to a working parser...

Is it valid to do compile-time constant folding as an optimization?

I know statements like

   a = 1 + 2

may have interesting runtime behaviours if addition is overloaded for 
fixnums, but is that guaranteed, or is it OK if the compiler reduces 
that to

   a = 3

?
