For example, checking loading files and so on. Also we want to know what kind of methods are defined. For both purpose, we can use some hook methods such as `Module#method_added` and so on. However, defining methods we can override this features. So that if we have two tools/libraries using this feature, they can be conflicted. # Proposal Introduce new TracePoint events: * `loaded` (invoked after `require`/`load`) * `method_added` (invoked after method definition) Also the following methods can be added: * Active only `loaded` event: * `TracePoint#loaded_feature` returns feature name. * `TracePoint#loaded_iseq` returns `RubyVM::InstructionSequence` object (MRI only, internal feature) # Optional proposal Add `class_added` alias name for `class` event. -- https://bugs.ruby-lang.org/ Unsubscribe:
