<pre class="notranslate">As of <a href="https://golang.org/cl/6454150/" rel="nofollow">https://golang.org/cl/6454150/</a> (rev a14ef77ab98c), this program no longer
parses correctly:
  package x
  import "time"
  const μs = time.Microsecond

The "μs" is not present in the AST.

I'll have a quick dig into it, and punt to gri if I can't figure it out soon.</pre>
<pre class="notranslate">What steps will reproduce the problem?
1. Run the simple echo server here: <a href="http://pastie.org/783355" rel="nofollow">http://pastie.org/783355</a>
2. On a separate console, run the simple program that creates a new
throwaway connection to the server every second: <a href="http://pastie.org/783368" rel="nofollow">http://pastie.org/783368</a>

What is the expected output? What do you see instead?
The server will continue to print "client connected", but they are never
closed by the garbage collector. If this program keeps running, the system
will eventually run out of sockets.

I believe the garbage collector should call close() on sockets which are
garbage collected
