          Issue ID: 16357
           Summary: cast(T[])[x] casts x to T instead of [x] to T[]
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: wrong-code
          Severity: normal
          Priority: P3
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: thecybershadow gmail.com

////////////// test.d //////////////
void main()
{
    uint x;
    ubyte[] data = cast(ubyte[])[x];
    assert(data.length == 4);
}
////////////////////////////////////

This is surprising, because if the expression is split up into:

    auto arr = [x];
    ubyte[] data = cast(ubyte[])arr;

then the result is as expected (an array with 4 elements).
