[IPython-dev] [ANN] IPython 3.0.0rc1

[Michael Waskom]

Hi, sorry to be a nuisance, but I'm worried this part of my second email
may have been overlooked, and it's been bugging me a lot as I've been
working with the release candidate:

One other thing I have noticed is that, when shift-TABing to get the
function docstring popover in the notebook, the help seems often bound to
objects that have been added as arguments, and not  to the function
itself., i.e.

func(a, b, [shift-TAB]

will show me the docstring for the object that `b` points at, although this
seems to only happen when an variable is being used. In other words,

func(a, "b", [shift-TAB]

will show me the docstring for `a`.

Previously this would happen when using a function within the call, ie.e.

func1(a, func2(b), [shift=TAB]

would should me the docs for `func2` (even if I had closed parens on it).
But the behavior has changed somewhat.
