Translating smalltalk code into native code requires an abstraction
layer, i'm yet missing :)

I know what you asking, like, if you can code like this:

myNativeMethod: foo with: bar

  ^  foo readByte + bar * self

(I following this way , but in another project - Moebius ;) ).
Sure, it can be possible to use it. And i slowly moving in that direction.
The infrastructure in Moebius is following:

(a)(Smalltalk parser) -> (b)(Native intermediate instructions
generator (compiler)) -> (c)(Native code translator)
-> (d)(AsmJit)

I having a, b and d , but c is still not complete.
And sure thing, one can use it for own purposes , since Moebius
implemented purely in smalltalk,
and works in Squeak/Pharo, so potentially it can be retargeted to anything else.
