// bug with forward
// java.lang.NullPointerException
// at
// edu.ucdavis.jr.trans.sun.tools.javac.comp.Attr.visitForward(Attr.java:1771)
// ...

// cause: forwarded within
// an inni whose op is a 1-dim (or 2-dim, etc.) array.
// we hadn't used or tested that ;-(  so we do now ;-)

// no bug if used workaround with cap, e.g.,
// cap void (int, int, int) xx = foyer[0][0];
// inni void xx(int id, int src, int dst) {

// similar bug with reply

// so here are a bunch of tests for forward, reply, and return
