I haven't read the whole changelog yet, so this might not be a bug.
Pretty convenient when it worked though..

Seems the issue is triggered by using *char front(). Other types still work.

import std.stdio;

struct S {
    void popFront() { }

    @property char front() {
        return 'a';
    }

    @property bool empty() {
        return false;
    }
}

void main() {
    writeln(S()); // range.d(295): Error: static assert  "Cannot put a 
S into a LockingTextWriter"
}
