(And it does not allow you to set a default value on the variadic.) Given that any variadic function may be called with no arguments in the variadic section, it seems like this should be permitted after a default argument. (And indeed, variadic functions with no type specifications seem to work fine.) example code: //gives "Error: default argument expected for argv" void func1 (size_t argc = 0, string[] argv...) { } import core.vararg; //Does not issue an error. void func2 (size_t argc = 0, ...) { } void main() { } --
