While it's not documented in the spec, this feature is already documented in an
example in std.range.enumerate:

http://dlang.org/phobos/std_range.html#.enumerate

foreach (lineNum, line; stdin.byLine().enumerate(1))
stdout.writefln("line #%s: %s", lineNum, line);

So I think it's better to not document this anti-feature.

I'm not sure its such an anti-feature - I keep having cannot infer argument
types bugs using foreach on custom ranges, and zipping them with an
enumeration sequence beforehand seems a pleasant nice enough workaround.

(To be fair this may be fixed in 2.067 but I don't know because 2.067 segfaults
on my codebase and I haven't had time to hunt down the cause yet.)

In any case I feel it should either be documented or removed because it caught
me by surprise and took a little bit of time to figure out what was going on,
mainly because the lack of documentation.

In Issue 9817 I have suggested to remove that syntax, and replace it with
something more explicit and more flexible.
