Always allow code before super call when it does not use "this" · Issue #8277 · microsoft/TypeScript

The TypeScript specification currently reads: The first statement in the body of a constructor must be a super call if both of the following are true: The containing class is a derived class. The constructor declares parameter properties or the containing class declares instance member variables with initializers. It is reasonable in TypeScript to not permit this to be referenced in a constructor
