compiler assert when referencing varargs in return type expression

[tgschultz]

const std = @import("std");

pub fn foo(args: ...) @typeOf(args[0]) {
    return args[0];
}

test "" {
    const x = foo(i32(1), i64(2));
}

This should ultimately be fixed by #208.

It looks like args should be comptime since @typeOf is used on them. Should this be a compile error?

What's this I found, a var args bug report? Solved by deleting var args from the language!

const std = @import("std");

pub fn foo(args: var) @TypeOf(args[0]) {
    return args[0];
}

test "" {
    const x = foo(.{ @as(i32, 1), @as(i64, 2) });
}
