Is there a way to avoid the overhead of creating the args table for
every call? What other optimizations are possible?
From what I'm seeing you don't need a table, all you need is, well,
runtime checks.
Runtime checking the number of args passed is a bit more tricky, but
can still be done easily by adding a parameter to the compiled
function. Our previous example
def f(a=0, b=12):
# code here
then becomes
function f(num_args, a, b)
if num_args > 2 then
raise an error
end
if b == No_Arg_Passed then
b = 15
end
end
