As mentioned in the issue, when re-implementing function calls, you have
to flatten the arguments into a simple argument list (because the
function parameters are actually a sequence (*), despite Python's rich
function call possibilities).

(*) at least for pure Python functions, where the arguments are simply
pushed sequentially on the ceval stack
