However, that still would require something like

  $str[0..mb_strlen($needle)-1] == $needle

One advantage of the new functions over userland implementations would
be efficiency.  A strpos() would still require to search the whole
string if the $needle is not found.  substr() and string slices would
require a copy unless that would be optimized, if a general optimization
is possible at all.

Not sure, if I like to see yet two more string functions in the global
namespace, though.
