(*
   This is the big one.
   Once you get inside a function, all code is generated (recursively) as a "expression".
   "retval" is tracked to determine whether the value on an expression is actually used.
   eg, if the result of a block (ie, the last expression in the list) is used, then
   we have to do some funky stuff to generate a local function.
   Some things that change less often are stored in the context and are extracted
   at the top for simplicity.
