std.conv.to really should support it, that seems like a bug.

But just FYI, doing string-to-int conversions is pretty easy (this 
doesn't handle overflow, but you can use core.checkedint to deal with it 
if necessary):

```d
int parseInt(string s) nothrow @safe @nogc
{
    bool isNeg = false;
    assert(s.length > 0);
    if(s[0] == '-') {isNeg = true; s = s[1 .. $];}
    int result = 0;
    foreach(c; s) {
       assert(c >= '0' && c <= '9');
       result = result * 10 + (c - '0');
    }
    return result;
}
```
