# Note that you don't have to do the aliases if you use defaults, it
# just speeds things up the first time the sub runs, after that
# methods are cached.
# But it's still handy, since you explicitly specify which subs from
# the parent package you are using

# META: if the ISA search results are cached on the first lookup, may
# be we need to alias only those methods that override the defaults?
