 There is a ruby intel assembler called wilson out there. Or then there is Metasm, with
 good support for many other cpu's (and a lot more code)

+Is admittedly a little more fun, but also not really my personal goal in the near future.
 
 If i am really honest about this, i think ruby is a little quirky around the edges and i
 think a lot of that can/should be done as a compatibility layer. Keeping the core clean (and shiny).

 Stdlib is not clean. More like a layer that accumulated over the years.

+## Concurrency
 
 Solving concurrency is up for grabs. Any solution is a start, channels ala go are nice and
 lock free stuff is the ultimate goal.

+## Stary sky

+Iterate:
+
+1. more cpus (ie intel)
+2. more systems (ie mac)
+3. more syscalls, there are after all some hundreds (most as external gems)
+5. A lot of modern cpu's functionality has to be mapped to ruby and implemented in assembler to be useful
+6. Different sized machines, with different register types ?
+7.  on 64bit, there would be 8 bits for types and thus allow for rational, complex, and whatnot
+8. Housekeeping (the superset of gc) is abundant
+9. Any amount of time could be spent on a decent digital tree (see judy). Or possibly Dr.Cliffs hash.
+10. Also better string/arrays would be good.
+11. The minor point of threads and hopefully lock free primitives to deal with that.
+12. Other languages, python at least, maybe others
+
+And generally optimise and work towards that perfect world (we never seem to be able to attain).
