mixin not overloading other mixins, Bug or feature?

[Travis Boucher]

float func1(float[2] v) { return v[0]; }
float func1(float[3] v) { return v[0]; }

template Test (size_t S) {
	float func2(float[S] v) { return v[0]; }
}

mixin Test!(2);
mixin Test!(3);

void main() {
	float[2] a2;

	func1(a2);
	func2(a2);
}


Here the call to func1 is fine, but the call to func2 results in a conflict.

Test!(2).func2 conflicts with unit.Test!(3).func2

This was tested with ldc (dmd 1.051).

Is this a bug or a "feature"?
