no, absolutely not.  it has no effect at run-time and does not appear in the
dis files or anywhere else at run-time.   all it does is suppress a diagnostic
at compile-time, so that a programmer who is anxious to avoid creating
cyclic data (if only by accident) can have that checked at compile time, and
it provides a similar cue for a reader.  on the other hand, the presence
of cyclic does not mean it will necessarily be cyclic, just that the compiler
cannot determine it will not.
