           Summary: Compile time array literal from a tuple
           Product: D
           Version: 1.009
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: jmjmak@utu.fi


template T(E...) { alias E T; }

// Error: cannot implicitly convert expression (tuple(1,2))
// of type (int, int) to int
//int[] a = [ T!(1,2) ];

// Error: cannot implicitly convert expression (tuple(1))
// of type (int) to int
//int[] a = [ T!(1) ];

struct S {
  // Error: cannot implicitly convert expression (tuple(1,2))
  // of type (int, int) to int
  //static int[] a = [ T!(1,2) ];

  // works
  static int[] a = [ 1,2 ];
}

// works
int[] a = [ 1,2 ];

void main() {
  // works
  int[] a = [ T!(1,2) ];

  // works
  int[] b = [ T!(1) ];

  // Error: cannot implicitly convert expression ([1,2])
  // of type int[2] to int
  //auto c = [ T!(1,2) ];

  // Error: tuple index 1 exceeds 1
  // Error: cannot implicitly convert expression ([1])
  // of type int[1] to int
  //auto d = [ T!(1) ];
}

I suppose they all should work. It's possible to do (on the global scope)

//int[] a = [ T!(1,2)[0], T!(1,2)[1] ];

but an arbitrary length tuple does not compile.

https://github.com/D-Programming-Language/dmd/commit/0e6f6211aef226d913a3c29f3ff3f11a420cdf41 Issue 1064 - Tuples are not expanded in array initializers

Expand any tuples in place. expandTuples from expression.c cannot be used because this is an array of ExpInitializers, not Expressions.
