This is already optimised in Cython/Compiler/Optimize.py ("tailmatch"),

method table in Builtins is clearly limited.
I'll look at doing this in Optimize.py. The hunk of my patch below
fixes a generic bug, though. Without it a utility function for a method
is used, but the definition of it is never injected into the C file.
