void foo(ref const int x) {} // OK
void bar(const ref int x) {} // OK
void main() {
    foreach (ref const int x; [1, 2, 3]) {} // OK
    foreach (const ref int x; [1, 2, 3]) {} // error
}


DMD 2.061alpha gives:

test.d(5): Error: basic type expected, not ref
test.d(5): Error: no identifier for declarator const(int)
test.d(5): Error: found 'ref' when expecting ';'

This is a dup of issue 4090.

 This is a dup of issue 4090.

At first sight it doesn't look like the same issue, because here I am listing
all the types and modifiers. "const ref int" is refused, while "ref const int"
is accepted. In both cases no type inferencing is required.

While in issue 4090 I put "const ref" so some type inferencing was required.

In the end if you think it's the same issue feel free to close this issue as a
duplicated. Thank you.

As I explained in the issue, it's current grammar limitation, and it doesn't
matter whether a type inference is required.

So I'll change this to 'resolved duplicated'.
