Your definition can allocate because STING_ELT can allocate.
getAttrib can GC in general. Currently it would not GC or allocate in
thi
Note that your desire is by definition impossible - as your example also shows
checking for S4 inheritance involves evaluation and thus allocation which
cannot be avoided by the dynamic design of S4 inheritance.

AFAIR getAttrib() can allocate as well. Also, R API functions that do
not allocate today, may allocate in the future.

Thank you Luke.
That is why I don't use Rf_inherits but INHERITS which does not
allocate, provided in the email body.
I cannot do similarly for S4 classes, thus asking for some API for that.
