BetterC Bug? Intended Behavior? Asking Here As Unsure

[Kayomn]

Something discovered in the D Language Code Club Discord server 
with the help of Wild is that the following code:

struct Test { ~this() {} }
void tester(Test test, Test[] tests...) { }

extern(C) void main() {
     tester(Test(), Test());
}

Raises the "TypeInfo cannot be used with ~betterC" error. It 
seems to be due to an inclusion of both the destructor and the 
non-vararg and vararg argument matching from testing.

Anyone know a way around this without resulting to the rather 
hacky solution of just having 1 argument and always assuming that 
at least 1 argument is present?

Here is a code demo setup for demonstrating the potential problem:
