use keyword only args where appropriate (original) (raw)

we should use keyword only arguments for some of our functions that have large numbers of kwargs to make it harder to make mistakes in the calling conventions, a prime example is [read_csv](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_csv.html?highlight=read_csv#pandas.read_csv].

likely we want a signature

def read_csv(self, filepath_or_buffer, *, .......

IOW all args, except for the first should be kwargs.

We could further modify a fair number of functions, so will treat this as a tracking issue.
