Okay, the key appears to be here:

funct2(123); //a function call

void funct2(A...)(A a)
	{
	enum hasRotate = isIntegral!(a[0]); // NOPE!
         }

//E: template instance isIntegral!(_param_0) does not match 
template declaration isIntegral(T)

But if I do:

funct2!(123); //note !

I get

//E: tuple A is used as a type
