As of 2.047, to be a forward range one has to have a .save() method.

std.algorithm.Until does not have one, but should be a forward range.

I've also noticed randomCover has the same problem.  Maybe rather than create a
separate bug report this one could list the ranges in phobos that need a
' property typeof(this) save() { return this; }' added?

(In reply to comment #1)

Yeah, I meant to scan std.algo but one of my daughters got sick and... well.

You could list other ranges that have the same problem, but in this case I need
to change the bug report's title.

...

OK, done. Go wild.

std.numeric: GapWeightedSimilarityIncremental
std.random: LinearCongruentialEngine, MersenneTwisterEngine, RandomCover,
RandomSample
std.range: Radial, Repeat, Cycle, Recurrence, FrontTransversal, Transversal
std.regex: Regex
std.regexp: Splitter
std.algorithm: Filter, Splitter, Uniq, Group, Until, SetUnion, SetIntersection,
SetDifference, SetSymmetricDifference
std.container: SList(T).Range

This list is of any structs that define popFront and do not define save, and
seem to support copying.  I've excluded any types with allocated storage,
unless they define a copy constructor.  I've also excluded any that are
obviously designed to be input ranges (have a File handle etc) but a couple may
have slipped through.

Changed the title to reflect that this report covers all of phobos, not just
std.algorithm.

According to David Simcha's commcent in bug 4362, repeat and cycle have already
been fixed in svn.  This leaves:

std.numeric: GapWeightedSimilarityIncremental
std.random: LinearCongruentialEngine, MersenneTwisterEngine, RandomCover,
RandomSample
std.range: Radial, Recurrence, FrontTransversal, Transversal
std.regex: Regex
std.regexp: Splitter
std.algorithm: Filter, Splitter, Uniq, Group, Until, SetUnion, SetIntersection,
SetDifference, SetSymmetricDifference
std.container: SList(T).Range

Fixed SVN.  (At least I think I got all of them.)
