Docstring for Series missing description on 'fastpath'

[jess010]

The Series docstring does not include any description for the 'fastpath' parameter.

Couldn't find any example on the website that used this parameter, not sure which needs updating: the init definition or the parameters section.

this an internal parameter

prob should be called _fastpath

would accept a pr to doc this

I can own the PR for this. I'm a little mystified though as to the purpose of this parameter, and why the init def'n would contain a variable that the user never modifies.

Are you able to elaborate on this?

[jreback]

it's an internal parameter

create a DataFrame
select a series
insert as a column to the frame
it's already created so it can be fastpathed and avoid some overhead

it doesn't matter to the user except perf wise
user shouldn't touch it

you'll have to explore the internals
