/**
    This macro ensures that the global @a function with 0, 1, 2 or more
    parameters (up to some implementaton-defined limit) is executed on scope
    exit, whether due to a normal function return or because an exception has
    been thrown. A typical example of its usage:

    @code
    void *buf = malloc(size);
    wxON_BLOCK_EXIT1(free, buf);
    @endcode
