Is there a way for nim to tell me when: * I can remove an import (unused imports) * I can convert a proc to a func (for procs that don't have site effects) * I can convert a var to a let (for variables that are only assigned once) * I can convert a let or var to a const (for variables in outer scope that don't change ever) * I can use .high instead of .len - 1
Should this be part of nimpretty?
