Fancy-translate

Pseudo-translate an ACL2 form into a term using fancy-ev to evaluate macros.

Signature

(fancy-translate x reclimit interp-st state hard-errp aokp) 
  → 
(mv errmsg val new-interp-st new-state)

Arguments

reclimit — Guard (natp reclimit).

interp-st — Guard (interp-st-bfrs-ok interp-st).

Returns

val — Type (pseudo-termp val).

Fancy-translate allows translation of untranslated terms into translated form, much like ACL2's translate family of functions, but without many complicated features.

Fancy-translate is highly simplified relative to ACL2's translate. It doesn't check executability constraints, stobj discipline, or even arity of function calls. It supports let, mv-let, and macroexpansion, but not flet, macrolet, loop$, df values, translation of lambda$ objects, and many other complications.
