I'm not sure I understand what you mean. The objects that make my
expressions are either local (things like sc_int) or global (things
like left). So in something like meta_eval(left(_1), i4+i32,i32) used
as it was used in the code I've posted there would be global
"constants" like left and _1 which are grabbed by reference for
building expressions and local objects like i4 and i32.
