Hello Jon,


where have you been for such a long time?

It seems, your destructive ages of blaming OCaml-team
instead of implementing things by your own, are now gone
(or at least on decay).

Seems you are back on the constructive side.
Nice to meet you at this place. :)

Fine. :)

cool. :)


We wait for the day, when it's faster than assembler. ;-)

You mentioned LLVM is using 3-op-code.
Interesting. Since a while I thought about using such
a language level for own implementations, but it was not more
than idea on using it.

To have the LLVM-project implementing this is fine.
This makes the start easier.
Seems to be interesting and mature enough to use it.


Ciao,
