For the record, the string mixin workaround looks like this:
version (D_Version2) {
mixin("alias const(char)* c_str;");
} else {
alias char* c_str;
}
You can find this code near the top of the Python header.

So far as I can tell, I was the first person to come up with (or at
least use) this workaround, but others may have come up with it on their
own.
