And is there also a pragma omp critical analogon?

For critical sections you could use a low-level mutex. I don't do
much parallel stuff in D, so I don't know if this is the
preferred way, but it's an option.

If it were (range, seed) then there would be no problem:

My thoughts exactly.
While fiddling with this I came across something that seems odd
in the behaviour of reduce and wondered if it's intended. It
rather limits the usefulness of reduce with UFCS to a + b and
a - b.
Reduce works correctly when provided with a seed argument:
reduce!a + b + 2(0, [1,1,1]).writeln;
A typical use case is to find the maximum of a range (there is
an example of this in the documentation at
http://dlang.org/phobos/std_algorithm.html#reduce). If you don't
know the highest possible value of elements, then you couldn't
come up with an appropriate seed for this case.
