Start all of your commands with a comma (2009)
Clever trick.  Too bad there's no good way to namespace commands. It would be interesting if you could have, for instance:<p><pre><code>  $ mkdir -p /tmp/bin/my
  $ printf '%s\n%s\n' '#!/bin/sh' 'echo hello' > /tmp/bin/my/hello
  $ chmod 755 /tmp/bin/my/hello
  $ PATH="/tmp/bin:$PATH"
  $ my/hello
  hello</code></pre>
