What is the scope of "Linting"

[imciner2]

One thing that I think would be useful to pin down is, what is the scope of what we want this "linter" tool to accomplish, since I think sometimes there can be some differing opinions about exactly what goes into a linter.

For starters, I am assuming there is a goal to eventually include some static analysis parts? e.g., unused variables and the like?

What about parts that are against the standard (so flagged by compilers as errors), but might still be interesting - e.g., duplicate case values in a select statement?
