ah! well, for all my python documentation reading, this is the first i have encountered this!

then, perhaps, the "bug" is this special indication is not obvious enough?

it is a quite important to understanding the definition in struct.unpack_from(), but no special reference is made.

thanks for writing back!

Thanks for your time to report this issue! Appreciated.

This slash is the syntax for positional-only parameters [1], the
paramters on the left side of the slash can only be given by position
(not by name), which is the case here, see:

>>> unpack_from(format="c", buffer=b"a", offset=0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unpack_from() takes at least 1 positional argument (0 given)

So I see no error here, if I missed something, don't hesitate to tell me.
