When providing a delegate to the std.range.put() function, compilation fails.
import std.range;
void main() {
string[] nameList1 = ["Anders", "David", "James", "Jeff", "Joe"];
void mySink(in char[] a) { }
auto r = &mySink;
static assert(isOutputRange!(typeof(r), string)); // Passes
put(r, nameList1); // Fails
}
std/range.d(611): Error: static assert "Cannot put a string[] into a void delegate(const(char[]) a)"
------
This appears to be an issue of line 597
else static if ((usingPut || usingFront) && isInputRange!E && is(typeof(put(r, e.front))))
{
for (; !e.empty; e.popFront()) put(r, e.front);
}
Where it should be checking (!usingPut && !usingFront) as they refer to
usingPut: Use put method from struct or class.
usingFront: Output range is an InputRange and may accept assignment to front.
