Hi, Andrei,
Unfortunately, your code came through quite garbled -- probably some
weird interaction between your mailer and the mailing list software.
Could you please re-send your message as plain text?
You also didn't mention what version of X10 you were using, though
from the "!" in the signature of main() I assume it was X10 2.0.
