NAME
        CoerceMethod -- Perform method on coerced object.

   SYNOPSIS
        result = CoerceMethod( cl, obj, MethodID, ... )

        ULONG CoerceMethod( struct iclass *, object *, ulong, ... );

   FUNCTION
        Boopsi support function that invokes the supplied message
        on the specified object, as though it were the specified
        class.  Equivalent to coercemethoda(), but allows you to
        build the message on the stack.

   INPUTS
        cl - pointer to boopsi class to receive the message
        obj - pointer to boopsi object
        ... - method-specific message built on the stack

   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.
