The immutable objects are a concept only enforced by the C API.
So move checks only to that region.
This does assume that the rest of the code is careful not getting
into these internal methods on immutable objects, which something
we do, but have no way of enforcing (currently).
.
Some compilers don't like this:
../src/hb-aat-layout-common.hh:732:9: error: declaration of 'using StateTable = struct AAT::StateTable<Types, EntryData>' changes meaning of 'StateTable' [-fpermissive]
732 | using StateTable = StateTable<Types, EntryData>;
The state we are dealing with here is the previous state; so it should
cause unsafe_to_break before current glyph.
I'm surprised this wasn't caught by any tests. Guess we don't have any
fonts with fancy end-of-text forms.
There's no easy way to undo a "using namespace" in our sources, so by the time
we get to include hb-coretext.cc from harfbuzz.cc, we already have "using namespace OT"
active, which clashes with Mac headers.
Error was:

As suggested by Ned, just ignoring it.
warning: 'CTGetCoreTextVersion' is deprecated: first deprecated in macOS 11.0 - Use
-[NSProcessInfo operatingSystemVersion] [-Wdeprecated-declarations]
- Lookup::closure_lookups also checks if the lookups visited and sets the lookup to visited. If we set visited in 'recurse' then Lookup::closure_lookups will fail to recurse into the children of the lookup.
- Also when copying ChainRule's skip LookupRecord's that point to lookups which aren't retained. This matches FontTool's behaviour.
