Currently micropython-wrap depends on typeid (RTTI) to do a full type check, and for naming anonymous classwrappers.
This PR replaces the use of RTTI by a static object based hash for types to perform the full type check. Also anonymously wrapped types can optionally function without RTTI, by naming them
AnonymousClasswrapper.As a side note: I've also experimented with naming the anonymous wrapper via
__PRETTY_FUNCTION__, but getting this to work reliably across all toolchains and versions is a bit of a mess. If you want, I can still implement this though.I've also tried adding a CI test run for
-fno-rtti, but I've not worked with appveyor yet, so lets see if this worked.
