Good, I'm glad someone pointed that out. The canonical JAPH (as used by JAPH #0, namely me) produces precisely the string:
in reply to Re^3: Infinite JAPHs?
in thread Infinite JAPHs?
The comma comes from the fact that it was a sign-off at the end of my Usenet postings:"Just another Perl hacker,"
blah blah blah
print "Just another Perl hacker,"
(my normal dot-sig here)
