missing haskey, get, etcetera?

[stevengj]

If I have a Python dictionary object or similar:

julia> d = pyeval("{'foo': 1, 'bar': 2}", Main)
Python dict: {'foo': 1, 'bar': 2}

it would be nice to be able to use haskey(d, x) (by checking whether PyObject_GetItem returns NULL), get(d, x, default) (similar to this), etcetera.

Maybe call it pyhasitem if you don't want to overload haskey. You already have a 2-arg pygetitem, so you could add a 3-arg version instead of overloading get. (Though I'm not sure what's wrong with overloading haskey and get, since you already overload getindex.)

It works to wrap d in PyDict{Any,Any}(d), of course.

OK I've added pyhasitem, 3-arg pygetitem. I'm a little wary of this, as I try to stick to the Python API and these don't exist, but they are logical analogues of pyhasattr and pyhasitem.

Have used them to implement get, get! and haskey.

Thanks !
