--- Comment #2 from Kenji Hara <k.hara...@gmail.com> ---
Reduced test case:
auto aafunc(string k)
{
enum aa = [ "K": "V" ];
auto p = k in aa;
return null;
}
struct MapResult(alias fun, R)
{
R _input;
@property auto ref front()
{
return fun(_input[0]);
}
}
auto array(R)(R r)
{
alias E = typeof(r.front);
E[] result;
result ~= r.front;
return result;
}
auto mapfun(R)(R words, string k)
{
return array(MapResult!(s => aafunc(k), R)(words));
}
void main()
{
auto r = mapfun([""], "");
}
