check variable names
an option like "-hard" It will mark as mistake "else" and will mark as mistake all the 1 character variable aside those declared inside a for or if statement.
Can you name linters that would do this?
actually, there is none that I know, but I suppose a script that apply a regex looking for those is something possible to implement
Isn't this really a more general question about automated code analyzers for all Exercism languages?
would be really nice if get implemented for all the languages supported by Exercism :)
We will probably do something at some point about checking variable names. There are some naming guidelines that are enforced by linters and I would probably start with that.
Note that we are having discussions on this in the auto-mentor project: https://github.com/exercism/automated-mentoring-support/blob/master/docs/guidelines.md#approvability
