/**
    This family of macros allows to ensure that the global function @e func
    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

    Please see the original article by Andrei Alexandrescu and Petru Marginean
    published in December 2000 issue of C/C++ Users Journal for more
    details.
