This requires a long answer.   a very long answer.
More later, I must work this evening.

You are asking for water to roll up-hill.  If you want the joy of
hearing the cool ideas as Armin has them, you need to hang out on
the irc channel.  Of course, if you are interested in such things
this makes hanging out there worthwhile.

Of course, but if you think that Lennart Augustsson is not familiar
with every aspect of every Haskell compiler on the planet .... well
then I know Lennart better than you do.  And given that Lennart is
a friend, well really a good friend of my lover and a something-better-
than-an-acquaintance with me ---- I should make the effort to get these
two under the same roof (mine, by preference) for the fun of the
experience.

So thank you for giving me this idea ...
