Description:	The following script illustrates that tailcall does not trigger a handler set using `namespace unknown`. `namespace eval ns1 { proc u1 args { return hello } namespace unknown u1 } # this triggers the unknown handler puts [namespace eval ns1 nosuchroutine] # this does not puts [apply [list {} { tailcall nosuchroutine } ns1]]`
