[Python-ideas] Exact integral types in struct

The struct module works only with natural platform-specific integers. As
a result, a lot of code in the standard library and third-party
applications are forced either to rely on unreliable assumptions (short
is always 2-byte, long is always 4-byte), which is not always true,
either explicitly construct the integer from bytes
(b+(b<<8)+(b<<16)+...). I propose to introduce a special
notation formats for signed and unsigned integers of arbitrary exact
size (which is given a number preceded by the prefix). After that,
eliminate the use of platform-specific formats when working with
platform-independent data (such as zip, for example).
Or maybe I'm behind, and the corresponding functions already exist, and
the use of the struct module is only remnants?
