Hi everyone,
Technically r1 and r2 are different types of range. Isn't it
inconsistent to chain both? If not, why is the char type
converted to int?

It's not inconsistent if there exists a common type that both
range element types implicit convert to.
The real problem is the implicit conversion of char to int,
which I have been against for a long time. Walter, however,
disagrees.

```d
auto a = [97, 98, 99];
auto b = ['d', 'e', 'f'];
a.chain(b).map!(chr => chr.to!char).writeln;
// abcdef
```
Nice, there is a solution that requires memory allocation, but it
still makes you think!
However, they can fix this in Phobos3 because now we have this
too:

PS. I think I unintentionally made a chain by repeating the
source code above, sorry :)
