Fun with open() on a string
Message ID:
This very nearly qualifies as an easter egg.  Inspect the following:

    perl -e 'close STDIN; open STDIN, "<", \$x; print <>'

Guess what it does.  Run it.  See if you were right.

Bugworthy?  I don't know; maybe, that's why I mention it here.  But it had
some entertainment value for me today.
