The tag cl has just over 50 questions.
Many of them are about CL and OpenCL.
Many of them are probably tagged to represent the MSVC C compiler,
I've just rejected a suggested edit for a wiki that only allowed the MSVC meaning (with a custom explanation saying why, and saying it was time to discuss on Meta) — but it seems that other people thought it was OK.
What's best to do with the cl tag?
I note that there is a opencl with about 1300 questions; those questions about OpenCL could simply lose the plain cl tag. There are a variety of tags related to MS Visual Studio; I'm not sure if there needs to be a separate tag for
cl.exe per se.
