>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);
