NAME
        CoerceMethodA -- Perform method on coerced object.

   SYNOPSIS
        result = CoerceMethodA( cl, obj, msg )

        ULONG CoerceMethodA( struct iclass *, object *, msg );

   FUNCTION
        Boopsi support function that invokes the supplied message
        on the specified object, as though it were the specified
        class.

   INPUTS
        cl - pointer to boopsi class to receive the message
        obj - pointer to boopsi object
        msg - pointer to method-specific message to send

   RESULT
        result - class and message-specific result.

   NOTES
        This function first appears in the V37 release of amiga.lib.
        While it intrinsically does not require any particular release
        of the system software to operate, it is designed to work with
        the boopsi subsystem of Intuition, which was only introduced
        in V36.
        Some early example code may refer to this function as CM().
