The following example compiles work as expected: import std.stdio; import std.typecons; void main() { Nullable!(int) a; static if(is(typeof(a) == Nullable!(U), U)) writeln("true"); else writeln("false"); } But if I use the fully qualified name in the condition, i.e. "std.typecons.Nullable!(U)", then I get this compile error: main.d(8): Error: undefined identifier 'U' Shouldn't this work?
