/-! # Pure (non-IO) evaluator.
|
||
|
||
Mirror of octive-lean's `PureEval`. Strips IO so that the evaluator becomes
|
||
a `def` (not `partial def`) over a finite fuel parameter, suitable for
|
||
reasoning. The relationship to `Eval.evalExpr` is captured by `ValueEquiv`.
|
||
|
||
Stub for now — fill in once `Eval` is non-trivial. -/
