I think there are two different definitions of "late binding" in play here. The footnote makes it clear that the author considers C++ not to have "late binding" > Early binding allows for static verification of the existence of method-signature pairs (e.g. v-tables). Late binding does not give the compiler (or an IDE) enough information for existence verification, it has to be looked up at run-time.
