           Summary: NewExpression grammar is insufficient
           Product: D
           Version: D2
          Hardware: All

Consider the following reasonable D program:

---
void main()
{
    import std.stdio : writeln;
    int[][] var = new int[][](3, 2);
    writeln(var);
}
---

The relevant parts of the grammar:

NewExpressionWithArgs:
    'new' AllocatorArguments? Type '(' ArgumentListopt ')'
Type:
    TypeCtors? BasicType
    TypeCtors? BasicType AltDeclarator
AltDeclarator:
    BasicType2? Identifier AltDeclaratorSuffixes
AltDeclaratorSuffix:
    '[' ']'

"int[][]" cannot be parsed with the AltDeclarator rule because there is no
identifier between "int" and "[][]"
