full compilation to expr-opgen TODO:
|
||||
- word! and long! are a mess right now
|
||||
- I don't think word-at and long-at could use it
|
||||
|
||||
- Could custom forms compile to opgens?? What would this look like?
|
||||
* see far-ref - it's really a constant, there's no reason to stuff the result into the temporary register just to push it onto the stack
|
||||
* if you call expr-poly / expr-word / expr-long, then put it into the register
