Like uplevel 1 except that it also causes the current scope to terminate, though the command is looked up in the current context first. Consequence of NRE.
proc fred {} {
george
}proc george {} {
proc george {} {
tailcall harry
}If I call fred, it's almost as though fred called harry directly, instead of george. Not so? MS: yup - all traces of george are gone from the program stack when harry is MS yup - all traces of george are gone from the program stack when harry is called. Now, if harry resolves to a different command in george's current namespace than it would under fred's, the harry that is called is george's and not fred's (no diff if the commands are FQ, of course). I think this does pretty much what delegation is supposed to do, right?
