The example for appender located here, does not compile with GDC.
https://dlang.org/library/std/array/appender.html
void main()
{
import std.array;
import std.stdio: write, writeln, writef, writefln;
auto w = appender!string;
// pre-allocate space for at least 10 elements (this avoids
costly reallocations)
w.reserve(10);
assert(w.capacity >= 10);
w.put('a'); // single elements
w.put("bc"); // multiple elements
// use the append syntax
w ~= 'd';
w ~= "ef";
writeln(w[]); // "abcdef"
}
For the line "Writeln(w[]);" GDC reports "error: no [] operator
overload for type Appender!string".
It works with DMD.
Time to file a bug report with GCC-GDC?
