We could define a new expression that evaluates the the value of its  
LHS (unlike a comma) but is defined to evaluate the LHS before the RHS  
(like a comma).

That said, if you guys are all happy with a different approach, go for  
it :).  I thought that the destroyexpr thing was a simple way to model  
this, that's all.
