Unexpected result from [slave alias srcCmd {}]

[Erik Leunissen]

L.S.

I'm exercising aliases between master and slave interps. The following
gave an unexpected result, or I misunderstood something.

The unexpected part is that [slave alias srcCmd {}] should delete a
previously defined alias. What I find is that it deletes the command
itself in the slave interpreter. See below for a reproducible script.

Did I misunderstand the meaning of an alias, or is this a bug?

Greetings,

% interp create slave
slave
% proc putsFromMaster {txt} {
puts "Master: $txt"
}
% slave alias puts putsFromMaster
puts
% slave eval puts foo
Master: foo
% puts [slave eval info commands p*]
pwd pid proc package puts
% slave alias puts {}
% slave eval puts foo
invalid command name "puts"
% puts [slave eval info commands p*]
pwd pid proc package

I think the original command in the slave was deleted during
its "replacement" by the alias, not during deletion of the alias.

... and you are right.
