Sawscript panics when nominal types are used in baked in Cryptol libraries.

Problem

  • Originally, this bug manifests itself as described here Support importing Cryptol enums into SAWCore #2052 (comment), but the problem is not enums.

  • With some browsing around, we get the same panic when any nominal type (even struct, which should be supported) is used in any baked in Cryptol libraries that saw imports, e.g., deps/cryptol/lib/Cryptol.cry E.g., if one adds this code to that .../Cryptol.cry:

newtype Complex2 = { real2 : Integer, imag2 : Integer }
