Currently the naming scheme is a bit funky; the specializations are named after the original function followed by an arbitrary decimal number. This makes it hard to debug inlined specializations of recursive functions. With this patch I am adding ".specialized." in between of the original name and the suffix, which is now a single increment counter.
