tdpl: partial ordering of functions: conflict error

[Jerome BENOIT]

Hello List:

On my box, the following D source, inspired by the subsection 5.5.2 of tDpl, arises a `template conflict':

-----------------------------------------------------------------

T[] find(T, E)(T[] haystack, E needle)
	if (is(typeof(haystack[0] != needle) == bool)) {
	while (haystack.length > 0 && haystack[0] != needle) {
		haystack = haystack[1 .. $];
		}
	return haystack;
	}

TL[] find(TL, TS)(TL[] longer, TS[] shorter)
	if (is(typeof(longer[0 .. 1] == shorter) : bool)) {
	while (longer.length >= shorter.length) {
		if (longer[0 .. shorter.length] == shorter) break;
		longer=longer[1 .. $];
		}
	return longer;
	}

int[] find(int[] longer, int[] shorter) {
	while (longer.length >= shorter.length) {
		if (longer[0 .. shorter.length] == shorter) break;
		longer=longer[1 .. $];
		}
	return longer;
	}

unittest {
	long[] a1 = [ 6, 1, 2, 3 ];
	int[] a2 = [ 1 , 2 ];
	assert(find(a1, a2) == a1[1 .. $]);
	}

void main() {}

-----------------------------------------------------------------

And I cannot figure why :-(

Thanks in advance for any help,
Jerome
