Request for some kind of named arguments loc
Please quickly recall how awesome named arguments for Python are and then read through the following idea:

In case of identical or almost identical values of `index` and `columns`, it can be annoying to remember the assignment of the two data-axes to index and columns respectively. This could be solved by assigning names to `index` and `columns`, e.g. `index_name=y`and `columns_name=x`, and hence being able to retrieve values via `pd.DataFrame.name_loc(x=10, y=20)` (syntax not final).

I have no idea, if such a feature can be implemented with reasonable effort. I do however believe, that it would highly increase the usability of DataFrames for certain usecases.
