Description

Dear all,

it seems that no checks are implemented on the language variable defined as part of an Extension in setup.py. I can set it to language='jadshad' and the installation process would still work. For example, writing language='C++', the language is not correctly interpreted as C++ (it should be language='c++'). If you point me in the right direction (where to look in the repo), I would be happy to try to tackle this issue.

Best wishes.

Research direction

Start by tracing how the language value in setup.py is handled during extension installation. Check the existing tests around extension configuration, then define completion as rejecting unsupported values and handling the reported C++ versus c++ case consistently.
