import std.stdio: writeln;
import std.range: chunks;
void main() {
chunks("abcd"d, 0).writeln;
}
Prints an unbound range of empty strings, I think this is not good:
["", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "" ...
I suggest to refuse the chunkSize = 0 with a pre-condition (or worse with an
enforce).
An alternative solution is to make 0 a special case, and return the whole
iterable:
std.range.chunks("abcd"d, 0).writeln;
==>
["abcd"]
