My mistake was thinking the (JSObjectCallAsFunctionCallback) had to be
static, since in the Pong example, the function is static. I also
envisaged having the function as a member function, but it seems it
must be a free-standing function.

This worked, thanks for pointing out this function. I have only really
looked at the JSObjectRef library / functions.

This seems extremely useful. Can "private data" include e a C pointer
to an object?
