Specifically, VALUE (Sandbox::*)(VALUE).  Pointers to non-static methods
are actually a totally separate family of types to function pointers and
cannot be called without first using the .* or ->* operators to "bind"
them.  This is similar to the difference between UnboundMethod and
Proc/Method in Ruby.
