use dynops to implement M0 ops

Rewrite current print op in terms of M0 ops

Objects are just numbers, a la Smalltalk

Write M0 in terms of LLVM

No one optimized python for optimizability. That wasn't the point.

Simplest possble way in M0 to call C library?
    invoke function, arguments, returnvalue

Perl 5's syscall

Will GC be in M0 ?

Spec for M0 dependent on a model?

.NET could use their own GC.

Is alloc a part of M0?

Will the GC ever be written in M0 ?

We need temprorary storage in M0.

How do we store or get at a Context from M0 ?

Allison: I'm having a "Turtles all the way down" problem.

M1 - Context, contains:
     offset
        0  PC
        4  I
        8  N
        12 S
        16 P

M0 : PC = load CTX, 0, 4

Is there a single global context? interp->current_ctx

Is there just one PC? Or does every "thread" have their own?

Context PMC at M1 is a Continuation

Context as implicit 1st op to all M0 ops

Immutable context data structure

How to write fork() in M0 ?
