using a binary tree container

[Tom]

what with this?:
	auto arr = ["foo", "bar", "aaa", "zzz"];
	sort(arr);
	assert(canFind("foo"));
	assert(canFind("aaa"));
	assert(!canFind("aa"));
I had a "Error	1	Error: module algorithem is in file 'std\algorithem.d' which
cannot be read	main.d	"
when I tried to compile, so I couldn't check it.
