[SciPy-Dev] how to turn internal names into API and freeze them forever

The scipy.stats.distributions allow now keyword access to the shape parameters. Before, the names of shape parameters where just part of the signature, but couldn't be used in code, only positional argument where possible. Now, users can actually use them in their code. hypergeom uses `M,n,N` where I usually need to read the description for several minutes to remember what they are. most distributions use one letter parameters: Since I just checked numpy.random.triangular uses `mode` scipy.triang just uses `c` Josef
