FWIW, you can already run a MT foreach variation on the tools.threadpool
class, and it wouldn't be that hard to write a tree reduce that does the
same .. but I see your point and agree. In the end, programming
languages should come as close as possible to capturing your intentions
with a given piece of code, which is why this kind of metadata would be
extremely useful to a clever compiler.
