Bug 8278 – std.range.chunks for generic Forward Ranges?

From the online docs of std.range.chunks: This range iterates over fixed-sized chunks of size chunkSize of a source range. Source must be an input range with slicing and length. Is it possible to modify chunks() to allow it to also work on forward ranges that have no slicing and lenght? An example is chunking the output of recurrence(): auto r = recurrence!q{(22695477 * a[n-1] + 12345) % 1073741824}(123456789U); auto c = std.range.chunks(r, 5);

Works in git HEAD: ----- import std.range, std.algorithm; void main() { struct FwdRange { // N.B. no slicing or length here enum empty = false; auto front = 1; void popFront() {} @property auto save() { return this; } } auto c = std.range.chunks(FwdRange(), 5); import std.stdio; writeln(c.take(10)); } -----
