Feature or enhancement

Proposal:

We should use recorded values instead, as that is not bounded by a limited-size cache, and it will be easier to make the optimizer thread safe for FT. See for example how I use recorded values for guards in this commit 8fab9d3

Ops that need converting:

• _CHECK_ATTR_CLASS
• _GUARD_TYPE_VERSION

@NekoAsakura would you like to work on this?

Has this already been discussed elsewhere?
