Having an obscure type variable name is causing some pretty inscrutable errors. For instance: ``` xarray/core/utils.py:466: error: Value of type variable "_LT" of "sorted" cannot be "K" tornado/simple_httpclient.py:324: error: Value of type variable "_LT" of "min" cannot be "Optional[float]" ``` I think having a more descriptive type variable name here is better for user experience and helps address the "why" of an error.

I agree, I'm generally not too happy with the PEP 8 recommendation to give typevars very short names. |

clearer in the context of the stub than it is out of context in an error.
