That definition of `.parse()` definitely makes sense. Do you then think this is
out of scope for `Formatter` in general or just for `.parse()`?. Just for
reference, this is what I currently use to get automatic numbering to work for
my use case.

Sascha Desch added the comment:
Another thing that occurred to me is the question of what `.parse()` should do
when a mix of auto-numbered and manually numbered fields is supplied e.g.
`{}{1}`. As of now `.parse()` happily processes such inputs and some other
piece of code deals with this
Sascha Desch added the comment:
Yes it should return a string containing the index of the positional argument
i.e. `"0"` so that it is compatible with `.get_field()`. Side note: It's a
somewhat weird that `.get_field` expects a string while `.get_value` expects an
int
New submission from Sascha Desch :
It appears when adding auto-numbered positional fields in python 3.1
`Formatter.parse` was not updated to handle them and currently returns an empty
string as the field name.
```
list(Formatter().parse('hello {}')) # [('hello ',
