in reply to Re^2: JAPH palindrome.
in thread JAPH palindrome.

I'm a bit surprised darwin doesn't like that. Anyway, here's a modification that doesn't use anything after '/usr/bin/perl' on the same line:
#!/usr/bin/perl !m;;;print "Just another Perl hacker" ;s; "rekcah lreP rehtona tsuJ" tnirp;;;m! lrep/nib/rsu/!#
An alternative:
#!/usr/bin/perl print "Just another Perl hacker" ;!q!; "rekcah lreP rehtona tsuJ" tnirp lrep/nib/rsu/!#
