Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Given an AST, finds the sclass that directly(-ish) contains the provided node. This won’t match arbitrarily complex structures - it only searches the first level deep (no begins-in-begins, for example). This is in keeping with mutant generally not supporting ‘weird’ syntax. Descending into ‘begin’ nodes is supported because these are generated for the one-line syntax class << self; def foo; end
