no-op is available via the [tcllib] [control] structure module.
----
[AMG]: I'm not sure if this is how [tcllib]'s no-op is implemented, but it can be done very simply:
proc no-op {args} {}
I believe the [bytecode] compiler specially recognizes and optimizes this.
----
GraemeP: That is how tcllib does it. There is a discussion on [interp alias] about creating a no-op, and a command that just returns its args.
