perl -MO=Deparse is more informative: 
LINE: while (defined($_ = <ARGV>)) {
    @_ = $_;
}
sub BEGIN {
    foreach $_ (%main::) {
        eval '@{$_}=${@_}';
    }
}
{
    print "Just another perl hacker.\n" unless eval "@_";
}

The message 
Can't locate Term/ReadLine.pm in @INC (@INC contains: )

occurs because the BEGIN subroutine clobbers every global array variable including @INC. Clobbering @ARGV causes the while loop not to open any files (although as often as not I get the message Can't open : No such file or directory.). Clobbering @_ ensures that it evaluates as false so that JAPH will be printed.
