it's a simple thing that can easily be adapted to named-readtables,
and i'm willing to help doing that if things get moving on this front:


it's loaded with hu.dwim.def+swank.asd

we have a develop-op in hu.dwim.asdf that at the end looks for all the
*+swank systems, and loads them if all of their dependencies are
already loaded. (it also does a (declaim (optimize debug)), and
various other changes with logging, etc... depending on what system is
loaded with develop-op)

this reminds me of the general idea of backwards compatibility: people
who want to live without this feature can chose not to upgrade, as
always. or if they need the new stuff, then they can just patch asdf
locally to disable the enforcement of this. or asdf could even
accommodate this with a defsystem property that can opt a system out
of this otherwise useful isolation.

*or* this feature may not clearly be an improvement in general, but
i'm not convinced about that for now.

either way, if you use reader syntax in CL then you'll be neck deep
anyways into duct taping things together, unless an infrastructure is
set up that people agree to use.
