If copying into a separate list is a problem (memory-wise), re.finditer('\S+', string) also provides the same behaviour and gives me the sliced string, so there's no need to index for anything. Out of idle curiosity is there anything that stops MicroPython, or any other implementation for that matter, from providing views of a string rather than copying every time? IIRC memoryviews in CPython rely on the buffer protocol at the C API level, so since strings don't support this protocol you can't take a memoryview of them. Could this actually be implemented in the future, is the underlying C code just too complicated, or what?

Anybody?
