<h2 id="Roadmap">Go Roadmap</h2>
|
|
|
|
This page lists features and ideas being developed or discussed by the
|
|
Go team. This list will be updated as work continues.
|
|
|
|
<p>
|
|
The roadmap should be discussed on
|
|
the <a href="http://groups.google.com/group/golang-nuts">golang-nuts
|
|
mailing list</a>.

Language roadmap</h3>
|
|
|
|
<p>
|
|
This is a list of language changes that are being considered.
|
|
Appearance on this list is no guarantee that the change will be
|
|
accepted.
|
|
|
|
<ul>
|
|
<li>
|
|
Adjust and simplify semicolon rules.
|
|
<li>
|
|
Adjust definition of <code>...</code> in parameter lists.
|
|
<li>
|
|
Add explicit conversions from <code>string</code>
|
|
to <code>[]byte</code> and <code>[]int</code>.
|
|
<li>
|
|
Possibly rewrite restriction on goto across variable declarations.
|
|
<li>
|
|
Variant types. A way to define a type as being the union of some set
|
|
of types.
|
|
<li>
|
|
Possibly provide a method that will be run by the garbage
|
|
collector when an item is freed.
|
|
<li>
|
|
Generics. An active topic of discussion.
|
|
<li>
|
|
Exceptions. An active topic of discussion.
|
|
</ul>

|
|
<h3 id="Implementation_roadmap">
|
|
Implementation roadmap</h3>
|
|
|
|
<ul>
|
|
<li>
|
|
Improved garbage collector, most likely a reference counting collector
|
|
with a cycle detector running in a separate core.
|
|
<li>
|
|
Debugger.
|
|
<li>
|
|
Native Client (NaCl) support.
|
|
<li>
|
|
App Engine support.
|
|
<li>
|
|
Improved CGO including some mechanism for calling back from C to Go.
|
|
<li>
|
|
SWIG support.
|
|
<li>
|
|
Public continuous build and benchmark infrastructure.
|
|
<li>
|
|
Improved implementation documentation.
|
|
<li>
|
|
Package manager, possibly including a language change to the import
|
|
statement.
|
|
</ul>
|
|
|
|
<h4 id="Gc_roadmap">
|
|
Gc compiler roadmap</h4>
|
|
|
|
<ul>
|
|
<li>
|
|
Method expressions.
|
|
<li>
|
|
Support multiple packages with the same name (but different import
|
|
paths) in the same program.
|
|
<li>
|
|
Implement goto restrictions.
|
|
<li>
|
|
Safe compilation mode: generate code which is guaranteed not to obtain
|
|
an invalid memory address other than via <code>import "unsafe"</code>.
|
|
<li>
|
|
Generate ELF debug info.
|
|
<li>
|
|
Improved optimization.
|
|
<li>
|
|
5g: Better floating point support.
|
|
</ul>
