Some of the proposed struct module additions look far from straightforward; I
find that section of the PEP significantly lacking in details and motivation.
"Unpacking a long-double will return a decimal object or a ctypes long-double."
Returning a Decimal object here doesn't make a lot of sense, since Decimal
objects aren't generally compatible with floats. And ctypes long double
objects don't seem to exist, as far as I can tell. It might be better not to
add this code.
Another bit that's not clear to me: how is unpacking an object pointer
expected to work, and how would it typically be used? What if the unpacked
pointer no longer points to a valid Python object? How would this work in
other Python implementations?
For the 'X{}' format (pointer to a function), is this supposed to mean a Python
function or a C function?
What's a 'specific pointer'?
