           Summary: Cannot derive interface from empty type tuple
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: samukha voliacable.com



PDT ---
Empty tuple in an interface's base type list should be legal as it is with
classes.

import std.typetuple;

interface I {} // ok
interface I2 : TypeTuple!() {} // ok
interface I3 : TypeTuple!(I) {} // ok
class A : I, TypeTuple!() {} // ok
interface I4 : I, TypeTuple!() {} // fail

Error: interface a.I4 base type must be interface, not ()

Actually, the problem is with tuple flattening in general:

class A2 : I, TypeTuple!(I2) {} // ok
interface I5 : I, TypeTuple!(I2) {} // fail
