Right, byte order specifiers are always at the beginning of the string.
That is at least something. I wonder if we should tighten PEP-3118 to
demand a canonical form of format strings, such as (probably incomplete):
- Whitespace is disallowed.
- Except for 's', no zero count may be given.
- A count of 1 (redundant) is disallowed.
- Repeats must be specified in terms of count + single char.
That still leaves the '=I' != '=L' problem. Why are there two
specifiers describing uint32_t?
Anyway, as Meador says, this can get tricky and I don't think this
can be resolved before beta-2. I'm attaching a patch that should
behave well for the restricted canonical form at least.
