#   A method ought to work "the same" whether or not it has been overridden by
#   a subclass. A tailcalled command ought to have as parent stack the same
#   thing you'd get with uplevel 1. A subclass will often expect the
#   superclass's result to be the result that would be returned if the
#   subclass was not there.

# Common setup:
#	any invocation of bar should emit "abc\nhi\n" then return to its
#	caller
