How do I remove a tcl procedure?

One can

unset a variable,
override an alias with interp alias {} myproc {} otherproc,
override a proc with one defined inside another namespace with namespace import -force.

But I did not find a way to make a procedure unknown.

Answer

% proc myproc {} {

% myproc
hello world
% rename myproc ""
% myproc
invalid command name "myproc"
%
