Here is a fun and possibly useful solution (that works only on 0.4 due to
call overloading):

It introduces a `MultidimFunction` type, and a macro `@multidim` that works
as follows:
julia @multidim f(x) = [sqrt(x[1]), 2x[2]]
Since f1(x) requires a call to f(x), there's no way for your approach to
work in Julia. You probably should define f1(x) as sqrt(x[1]) and f2(x) as
2 * x[2].

You may expect the optimizer to completely omit calculating the first
element, but unfortunately for you, the negativity check before the square
root will never be optimized away, since it affects the whole program
execution and thus *shouldn't* be omitted from the compiled program, even
though
