I think, the bug is to be found in dmd and byKey is innocent. If not, the correct component is not phobos but druntime, because byKey is located there.

--- Comment #2 from Andrej Mitrovic <andrej.mitrovich@gmail.com> ---
Simpler example:

-----
import std.stdio;
import std.range;

struct Set
{
    auto walk () { return [].only; }
    alias walk this;
}

void main()
{
    Set set;
    writeln(set);
}
-----

It has to do with ranges, not specifically hashmaps as previously thought.

I think somewhere in the formatter it's probably trying to invoke walk() multiple times, implicitly through that 'alias this'.
