Bug 10175 – std.conv.to for a range

This is borderline between an enhancement and a bug report. import std.array: array; import std.range: iota; import std.conv: to; void main() { auto items = iota(10); auto r1 = items.array.to!(string[]); auto r2 = items.to!(string[]); } DMD 2.063beta7 gives: ...\dmd2\src\phobos\std\conv.d(276): Error: template std.conv.toImpl does not match any function template declaration. Candidates are: ...\dmd2\src\phobos\std\conv.d(332): std.conv.toImpl(T, S)(S value) if (isImplicitlyConvertible!(S, T) && !isEnumStrToStr!(S, T) && !isNullToStr!(S, T)) ...\dmd2\src\phobos\std\conv.d(445): std.conv.toImpl(T, S)(ref S s) if (isRawStaticArray!(S)) ...\dmd2\src\phobos\std\conv.d(461): std.conv.toImpl(T, S)(S value) if (is(typeof(S.init.opCast!(T)()) : T) && !isExactSomeString!(T)) ...\dmd2\src\phobos\std\conv.d(492): std.conv.toImpl(T, S)(S value) if (!isImplicitlyConvertible!(S, T) && is(T == struct) && is(typeof(T(value)))) ...\dmd2\src\phobos\std\conv.d(542): std.conv.toImpl(T, S)(S value) if (!isImplicitlyConvertible!(S, T) && is(T == class) && is(typeof(new T(value)))) ...\dmd2\src\phobos\std\conv.d(276): ...
