Call-ie return on behalf of caller?

Is there a way other than exceptions for a called function to
force the caller to return?
Specifically, I know the return type of the caller(its always
bool) and under certain circumstances I would like the caller to
just give up and return false if the called function fails. With
as little boiler plate as possible on the call site. In c++ I
could do it very easily with macros, but I am failing to see a
similar way to do it in D other than maybe string mixins but that
seems like a bit much to do every time I want to call this thing.
I would be willing to put some boilerplate code in the beginning
of the caller, I could just put that in a mixin.
I know exceptions are really what I should be using but they are
such a pain to work with. I don't want to have to put try catch
blocks every time I call the caller.
Any ideas?
