- No point doing the manual size unit conversion for add. Sorry, no new
tests since there is no way to generate a LoadField with a negative
offset from ruby code AFAICT. Careful with the `as` casts. -

That would avoid a copy, since CRuby doesn't do lazy substrings which don't share the same end. -

- Generating an object_id for any type other than T_OBJECT (and T_CLASS)
will inevitably allocate an IMEMO/fields objects, which isn't supported

- Yeah... Either way, with the object_id now stored in `imemo/fields`, generating an object_id for anything other than `T_OBJECT` will inevitably allocate an IMEMO.

I said previously, I generally agree, but the datadog gem is quite popular, so I think we should try to find a short term solution if we can. At least that's what I tried to do. -

- Encodings are RTypedData, not the deprecated RData. Although the
structures are compatible we should use the correct API. -

- This fixes a crash when the new shape after a transition is too complex;
we need to check that it's not complex before trying to read by index. -
