[v2] Variadic function parameters aren't considered in constructors

[FenekkuKitsune]

Is your issue related to a problem? Please describe.
When a variadic function parameter is specified i.e. FuncErr(p_errorValue, p_funcName, p_funcParams*), then called with more parameters than specified i.e. FuncErR(err, Stuff.SetParameterFloat.Name, p_prefix, p_parameter, p_value), AHK++ doesn't consider the variadic state of the last parameter and reports the call as a problem, expecting 0-3 params but got 5.

Describe the solution you'd like
AHK++ should consider variadic parameters and not report calls with incorrect parameter counts as problems.

This simple example taken from the v2 documentation runs without problem in AHK++ v6.7.1.

Join(sep, params*) {
    for index,param in params
        str .= param . sep
    return SubStr(str, 1, -StrLen(sep))
}
MsgBox Join("`n", "one", "two", "three")

@fade2gray you're right, that runs without problem. There must be another cause, then. The problems appear for me when I open VMR.ahk which is a library file for controlling Voicemeeter. I didn't code the file, naturally, but it has a variadic function for catching errors, and calls it multiple times in try/catch statements. It's possible that the cause is the fact that VMRError is a class, and the function that is variadic is the __New function for said class.

class VMRError extends Error {
    ...
    __New(p_errorValue, p_funcName, p_funcParams*) {
       ...
    }
}

The first two instances of the listed problems - of which there are 20 - is:

static SetParameterFloat(p_prefix, p_parameter, p_value) {
        local result
        try result := DllCall(VBVMR.FUNC.SetParameterFloat, "AStr", p_prefix . "." . p_parameter, "Float", p_value, "Int")
        catch Error as err
            throw VMRError(err, VBVMR.SetParameterFloat.Name, p_prefix, p_parameter, p_value)
        if (result < 0)
            throw VMRError(result, VBVMR.SetParameterFloat.Name, p_prefix, p_parameter, p_value)
        return result
    }

When it comes to using classes, things get a bit beyond my comprehension, but I see in the docs that the variadic parameters can be passed as an array, so maybe try something like...

static SetParameterFloat(p_prefix, p_parameter, p_value) {
        local result
        vParams := [p_prefix, p_parameter, p_value]
        try result := DllCall(VBVMR.FUNC.SetParameterFloat, "AStr", p_prefix . "." . p_parameter, "Float", p_value, "Int")
        catch Error as err
            throw VMRError(err, VBVMR.SetParameterFloat.Name, vParams*)
        if (result < 0)
            throw VMRError(result, VBVMR.SetParameterFloat.Name, vParams*)
        return result
    }

@fade2gray that would break the library, those are calls not function definitions. I'm also not looking to edit said library as a lot of it is over my head and I'm liable to break something. I just decided to report this because, to my comprehension, the code is valid it's just AHK++ is for some reason not recognizing the parameter is variadic lol
