On dmd 2.061 the following (illegal) program:

void main()
{
    class Int
    {
        int _val;        
        this(int val){ _val = val; }
    }
    Int[] sink;

    foreach(v; 0..5_000)
        sink ~= [cast(Int)v]; //12
    foreach(v; 0..5_000)
        sink ~= cast(Int)v; //14
}

Produces:
bug.d(12): Error: e2ir: cannot cast v of type int to type bug.main.Int
bug.d(14): Error: e2ir: cannot cast v of type int to type bug.main.Int

The awful 'e2ir:' part of message seems to only trigger if v is coming from
foreach variable.
