           Summary: ForeachType grammar does not allow 'ref' to appear
                    after type constructors

Example DMD-valid code rejected by language spec:
---
foreach (foo, const ref bar; qwer.tyuiop)
---

The grammar spec says this:

ForeachType:
    'ref'? TypeCtors? BasicType Declarator
    'ref'? TypeCtors? Identifier

Either the compiler should be changed to require that 'ref' appear first, or
the grammar should be corrected to allow 'ref' to appear after type
constructors.
