This should be explained further. Because the "Object>>cCoerce:to:"
message does not do anything ( the comments in the method tell us so
!!! ), it is not obvious at first glance how casting works for code
generation. It took me a few tries to learn to cast correctly.
Along these lines, C function local variable declaration should be
covered.
Thanks for your work,
