--- Comment #16 from Andrei Alexandrescu <andrei@erdani.com> ---
This bug has a simple fix - throw a runtime exception (e.g. by onUnicodeError)
instead of assert(0). We shouldn't change language rules on account of this.
Thanks!

--- Comment #17 from Steven Schveighoffer <schveiguy@yahoo.com> ---
There are two problems, one is that the OP's code compiles, the other is that it segfaults. Arguably, fixing the first problem will fix the second. But just fixing the second leaves other problems still intact.

Also, note that this succeeds, but likely does not do what the writer wants:

string s = "123456";
s ~= 7;

Guess what this does (yes, it compiles)?

s ~= 123456;

As Andrei suggested, here is the quick fix:
PR https://github.com/dlang/druntime/pull/1696

Language design changes should be discussed with Walter and Andrei in depth.
