Python would be another example. It's compiled into bytecode. It could conceivably be compiled into x86 machine code on-the-fly (think Psyco). It's just hard to do, but for the same reasons a static Python compiler to assembly would be hard to do; the REPL is not making things much harder here.
Does he think all statically typed languages are compiled-only and can't be run with an interpreter or from a REPL?
