Comment 7 for bug 1258257

I think I get what the purpose of the issue is, though. I was mistaken.

I guess a separate issue needs to be opened to somehow make it work better with variable and function names (ie. know how to decompose camelCaseVariables and underscore_variables and how to report back spelling issues). And it would only care about definitions, not usages, because you only care of a misspelling when you define something.
