This is so that Pry::CodeObject can return Pry::ClassCommand objects directly, this is impt
as we want slightly different behaviour than just Pry::WrappedModule(command_class), notably .doc should return
command help rather than comments above the command's class definition.
Pry::CodeObject::Helpers mixin provides the following methods:
command?
module_with_yard_docs?
real_method_object?
c_method?
which are then mixed into the code objects: Pry::Command, Pry::Method, Pry::WrappedModule, Pry::WrappedModule::Candidate
the '#' used to be interpreted as a comment and so only 'local' and not the associated method was looked up.
Fixed this by letting strings of the form /\S#\S/ pass through to Pry::Method lookup
