Allow params keyword in some cases even if it is not the last parameter

[gurkantuna]

I am aware that in the following usage, the compiler is waiting for the params keyword as the last parameter to find out which parameter is the beginning of the array.

void Foo(params string[] args, params string[] args2) {
   
}

Also, like the compiler, I cannot predict how to find start/end of array with the usage of as follows and I agree with it :)

Foo("ab","bc","cd","de");//it is not clear which parameter is passed to which array! 

But what if we change the type of the parameter?

void Foo(params string[] args, params int[] args2) {
   
}

Foo("ab", "bc", 1, 2); 

If you show me this, I would think the int array starts from the third parameter. But the truth is, although I can tell the end of the arrays, I don't expect the compiler to do that.

Above methods cannot be compiled caused by my wrong usage :

CS0231 Error-A params parameter must be the last parameter in a formal
parameter list

Can be compiled in the following case, but I think it's pointless to use an optional parameter since the parameter has to be passed.

void Bar(bool arg = false, params string[] args) {

}

Bar(false, "ab", "bc");

So I think the following usage is deterministic as the last parameter is already of boolean type. I mean, I just want to use the ``Bar` method like this :

void Bar(params string[] args, bool arg = false) {

}

Bar( "ab", "bc");

Maybe I'm missing something, but I think this usage should be allowed in the language.

P.S. My suggestion is, of course, eligible for only the non-object types and different types of non-consecutive parameters.

void Bar(params object[] args, bool arg = false){
   
}

void Bar(params string[] args, params string[] args2){
   
}
