This is probably total overkill, but what about instead of mangling to __lambda
+ an incrementing integer, replace the integer with the SHA hash of the
lambda's AST tree? As Andrei said, we cater only to the case where the two
lambdas are token-for-token identical, because the general problem of
equivalence between two arbitrary lambdas is uncomputable.
