TODO: <a href="https://golang.org/cl/140958">https://golang.org/cl/140958</a>: add new mode bit PreserveAST to control clearing of data in AST
To address some outstanding issues in <a href="/cmd/doc/"><code>cmd/doc</code></a>,
this package has a new <a href="/pkg/go/doc/#Mode"><code>Mode</code></a> bit,
<code>PreserveAST</code>, which controls whether AST data is cleared.

TODO: <a href="https://golang.org/cl/134075">https://golang.org/cl/134075</a>: add (*File).LineStart, which returns Pos for a given line
The <a href="/pkg/go/token#File"><code>File</code></a> type has a new
<a href="/pkg/go/token#File.LineStart"><code>LineStart</code></a> field,
which returns the position of the start of a given line. This is especially useful
in programs that occassionally handle non-Go files, such as assembly, but wish to use
the <code>token.Pos</code> mechanism to identify file positions.

TODO: <a href="https://golang.org/cl/33572">https://golang.org/cl/33572</a>: add Value.MapRange method and MapIter type
A new <a href="/pkg/reflect#MapIter"><code>MapIter</code></a> type is
an iterator for ranging over a map. This type is exposed through the
<a href="/pkg/reflect#Value"><code>Value</code></a> type's new
<a href="/pkg/reflect#Value.MapRange"><code>MapRange</code></a> method.
This follows the same iteration semantics as a range statment, with <code>Next</code>
to advance the iterator, and <code>Key</code>/<code>Value</code> to access each entry.
