static method is better than new builtin function, agree.

: Currently we have exception tree of classes inherited from OSError When we use C API we can call PyErr_SetFromErrno and PyErr_SetFromErrnoWithFilename[Object] functions. This ones raise concrete exception class (FileNotFoundError for example) looking on implicit errno value. I cannot see the way to do it from python.
Maybe adding builtin like exception_from_errno(errno, filename=None) make some value? Function returns exception instance, concrete class depends of errno value
I think a static method on OSError like .from_errno would be good.
