The any in std.algorithm is defined:

--------------
bool any(alias pred, Range)(Range range);

Returns true if and only if a value v satisfying the predicate pred can be found 
in the forward range range. Performs Ο(r.length) evaluations of pred.
--------------

I see that as very different from !empty.
