this would be a trivial impl, e.g.

obj = obj.copy()
obj.set_axis(...)
return obj

so if you'd like to do a PR (keeping inplace=True as the default) would be ok.

I would not be upset by making this inplace=None and having a warning if not specified, so that we could make inplace=False the default (e.g. return a copy). We did a similar change in .eval IIRC in 0.18.0

@jreback Ok, I started the change to set_axis, why is flake not running in CI?

Here is eval change you mentioned that I'm going to use as a guide:

I think it was removed by accident here: https://github.com/pandas-dev/pandas/pull/14516/files, but you did already put in back 52241a7 in the meantime?

This removes some code from the core structures & pushes it to internals,
where the primitives are made more consistent.

This should all us to be a bit more consistent for pandas2 type things.

* BUG: Use size_t to avoid array index overflow; add missing malloc of error_msg

Fix a few locations where a parser's `error_msg` buffer is written to
without having been previously allocated. This manifested as a double
free during exception handling code making use of the `error_msg`.
Additionally, use `size_t/ssize_t` where array indices or lengths will
be stored. Previously, int32_t was used and would overflow on columns
with very large amounts of data (i.e. greater than INTMAX bytes).

* BUG: Have object dtype for empty Categorical ctor

Previously we had a `Float64Index`, which is inconsistent with, e.g., the
regular Index constructor.

Previously these relied worked around the return type by wrapping list-likes
in `np.array` and relying on that to cast to float. These workarounds are no
longer nescessary.

This relied on `NaN` being a float and empty being a float. Not a necessary
test anymore.

* MAINT: Use set literal for unsupported + depr args

Initializes unsupported and deprecated argument sets with set literals instead of the set constructor in pandas/io/parsers.py, as the former is slightly faster than the latter.

Patches several spelling errors and expands current doc to a proper doc-string.

* BUG: Fixed regex in asv.conf.json (#17300)

In pandas-dev#17293 I messed up the syntax. I
used a glob instead of a regex. According to the docs at
http://asv.readthedocs.io/en/latest/asv.conf.json.html#regressions-thresholds we
want to use a regex. I've actually manually tested this change and verified that
it works.

* API: Have MultiIndex consturctors always return a MI (#17236)

* API: Have MultiIndex constructors return MI

This removes the special case for MultiIndex constructors returning
an Index if all the levels are length-1. Now this will return a
MultiIndex with a single level.

This is a backwards incompatabile change, with no clear method for
deprecation, so we're making a clean break.
