This can be an alternative:
template gen (alias fn) {
struct GenRes { //
import std.traits;
ReturnType!fn func;
enum empty = false;
auto front() { return func; }
void popFront() { func = fn(); }
}
GenRes gen() {
auto gen = GenRes();
gen.popFront();
return gen;
}
} unittest {
import std.range, std.random : uniform;
import std.stdio;
enum E : char { False = 48, True }
auto r = gen!(function char() => uniform!E);
r.take(12).writefln!"[%s]";
}
