Overview

Inert recorder is similar to a null object in the sense, that in response to almost all messages it returns self. But in addition, it records received messages along with their arguments and blocks (if given). Recoded messages are available via #recorded_messages reader, aliased #ρ (small Greek rho). Inert recorder does not require any arguments for initalization, but if they are supplied, they are silently recoded into @init_args (for arguments) and readers.
