I have a deftype that supports with-meta, but I can't figure out how to
support caret reader syntax.
To support with-meta, I include a "meta" field and implement IObj methods
"meta" and "withMeta". Seems to work just fine:
(with-meta (entity-map [:A/B] {:a 1}) {:foo "metadata here"})
But this doesn't work: ^{:foo "metadata there"}(entity-map [:A/B] {:a 1})
In LispReader.clj it looks to me like the MetaReader checks to see if
object is instanceof IMeta, ISeq (so it can call assoc) and IReference (so
it can call resetMeta). My deftype supports both of those interfaces, but
the methods are not called when I construct an object using caret syntax,
as above.
Can anybody shed some light on this?
Thanks,
Gregg
