Support rest parameters

[LiaoPeng]

I hope that variable parameters supported.

When I compiled the below codes.

function sum(...args: i32[]): i32 {
    let total: i32 = 0;
    for (let index = 0; index < args.length; index ++) {
        total += args[index];
    }
    return total;

}
assert(sum(1, 2, 3) == 6);

I got the errors.

ERROR TS2554: Expected 1 arguments, but got 3.

btw, the online studio was unavailable.

ERROR: Entry file 'main.ts' not found.

I have the following code:

export function add(...args: Uint32Array): i32 {
  return args.reduce((a, b) => a + b, 0)
}

I'm getting error "AS215: Optional parameter must have an initializer.":

When I try to add initializer:

export function add(...args = []: Uint32Array): i32 {
  return args.reduce((a, b) => a + b, 0)
}

Then I'm getting error "TS1048: A rest parameter cannot have an initializer":

That is kinda funny since it knows it's a "rest" parameter, and kinda says that it both: should have and shouldn't have initializer 😂
