[dev.garbage] runtime: determine if an object is public

local and public objects and act accordingly.

 Go is the work of hundreds of contributors. We appreciate your help!
 
 To contribute, please read the contribution guidelines:

+## Binary Distribution Notes
+
+If you have just untarred a binary Go distribution, you need to set
+the environment variable $GOROOT to the full path of the go
+directory (the one containing this file).  You can omit the
+variable if you unpack it into /usr/local/go, or if you rebuild
+from sources by running all.bash (see doc/install-source.html).
+You should also add the Go binary directory $GOROOT/bin
+to your shell's path.
+
+For example, if you extracted the tar file into $HOME/go, you might
+put the following in your .profile:
+
+	export GOROOT=$HOME/go
+	export PATH=$PATH:$GOROOT/bin
+
+See https://golang.org/doc/install or doc/install.html for more details.

-<h2 id="go-contrib-init">Automatically set up &amp; diagnose your development environment</h3>
 <p>
-  The <code>go-contrib-init</code> tool configures and debugs your Go
-  development environment, automatically performing many of the steps
-  on this page, or telling you what you need to do next. If you wish
-  to use it, run:
+Before undertaking to write something new for the Go project,
+please <a href="https://golang.org/issue/new">file an issue</a>
+(or claim an <a href="https://golang.org/issues">existing issue</a>).
+Significant changes must go through the
+<a href="https://golang.org/s/proposal-process">change proposal process</a>
+before they can be accepted.
+</p>
+
+<p>
+This process gives everyone a chance to validate the design,
+helps prevent duplication of effort,
+and ensures that the idea fits inside the goals for the language and tools.
+It also checks that the design is sound before code is written;
+the code review tool is not the place for high-level discussions.
+</p>
+
+<p>
+When planning work, please note that the Go project follows a
+<a href="https://golang.org/wiki/Go-Release-Cycle">six-month
+development cycle</a>. The latter half of each cycle is a three-month
+feature freeze during which only bug fixes and doc updates are accepted.
+New work cannot be submitted during a feature freeze.

+<p>
+You've <a href="code.html">written and tested your code</a>, but

-// The bug happened like this:
-// 1) The main binary adds an itab for *json.UnsupportedValueError / error
-//    (concrete type / interface type).  This itab goes in hash bucket 0x111.
-// 2) The plugin adds that same itab again.  That makes a cycle in the itab
-//    chain rooted at hash bucket 0x111.
-// 3) The main binary then asks for the itab for *dynamodbstreamsevt.Event /
-//    json.Unmarshaler.  This itab happens to also live in bucket 0x111.
-//    The lookup code goes into an infinite loop searching for this itab.
-// The code is carefully crafted so that the two itabs are both from the
-// same bucket, and so that the second itab doesn't exist in
-// the itab hashmap yet (so the entire linked list must be searched).
