This works fine:

This doesn't:

In order to return the result as a string it would require an
allocation. You have to request that allocation (and associated
eager evaluation) explicitly
string y = "Hello".retro.find('H').to!string;
However, I think to get the expected result from unicode you
need
string y = "Hello".byGrapheme.retro.find('H').to!string;
but I might be wrong.
Oh. I see you actually wanted strrchr behaviour. That's different.
