Variadic arguments

[aspizu]

variadic arguments for both functions and procedures

type must be value, structs not allowed

func printf(format, ...values) {

}

discussion: ... or * for syntax?

[aitchFactor]

Slight preference for ... because imagine if virtual pointers become a thing later on

[aspizu]

I agree that ... is the better choice — it's visually clear, and * risks being misread as a pointer dereference.

For implementation, I'm leaning toward padding each call site to a fixed argument count of N, where N = max(arity across all calls). Unused slots would be left empty. Length will be a last hidden argument, but this means that indexing is difficult, requires a huge ternary.

for printf, it should really be possible to iterate/index over values, so why not use a list that is bound to the function?
