Good! I'd like to suggest a name alternative though
#defined_at
IMHO #location is very general and #defined_at better expresses what's
being returned (at least from what I gathered should be the semantics
of this method). Usage would be
def foo(&b)
file, line = b.defined_at
$stderr.printf "calling block which was defined at %s:%d\n", file, line
b.call
end
Kind regards
