import std.traits;
void f1(string[] = null) {}
void f2(string = null) {}
static assert(is(typeof(ParameterDefaultValueTuple!f1[0]) == string[])); // OK
static assert(is(typeof(ParameterDefaultValueTuple!f2[0]) == string )); // NG
//////////////////////////////////////////////////////////////////////////////
The second assert fails. If the first assert is commented out, the second
assert passes.
This worked in DMD 2.060 and no longer works since DMD 2.061.
