Made a couple of efforts recently to simplify the iloc.__setitem__ and they all crash on the rocks of this inconsistency.

There's a problem here in that the use .iloc(axis=1)[foo]=bar won't actually work, so still need a better alternative.

But getting this done should be a very high priority for 1.5 as its a blocker for all kinds of inconsistency-fixing.

@jreback in the Feb call i think we agreed to move forward with this but there was some bikeshedding over the name of the replacement method. Do you remember what we landed on?

thanks @jbrockmendel yeah has been out here for a while :->

followup, i think we need .isetitem in the api docs (and maybe a mention in the indexing.rst as well)

[py312] Fix test_tensor.py (#46669)
aefdf5f 
## Why are these changes needed?
To upgrade to py312 we need to upgrade to `pandas>=2.0.0`. This upgrade
introduced a breaking change in the syntax of some of our code / tests:
> Changed behavior in setting values with df.loc[:, foo] = bar or
df.iloc[:, foo] = bar, these now always attempt to set values inplace
before falling back to casting ([GH
45333](pandas-dev/pandas#45333))

As a result we needed to update these uses of loc to do direct
assignment.
