You're using the wrong function; .among is intended to be used in the
cases where the list of values to search for are fixed or known at
compile-time.

If the values to search for changes at runtime, you want .canFind
instead. For example:

	if ([1, 2, 3, 4].canFind(3))
		writeln("found it!");

Or use .find if you need to retrieve the found value (e.g., if it's a
structure and you matched on only one field).

	auto r = [ 1, 2, 3, 4 ].find(3);
	assert(r.front == 3);
