Even for C/C++, we don't handle the simd stuff there (where we should be
expecting a different function types in those cases, ones following the
declare simd ABIs). So, essentially it is correct only on
non-x86/non-aarch64, because other arches don't have their declare simd
ABIs.
I now use: ", simd taits not handled".

I think this is not implemented yet, at least not in trunk.
We don't allow map(to:foo(234)[:32]) or map(to:bar()->x->y[5].z[3]) etc.
I somehow had the impression that I saw lvalues for 'depend', but while
they are more complicated, I think I did not see f()[1] etc. – For
mapping, I did see patches implementing stuff like 'z->x->y[5]' (which
are pending review) but I think that even those did not use a function
call on the left. Thus, a simple pilot error.

But it is stub only, though not sure if we in short term plan something
else. So perhaps ok.
I have now added "Stub only" to both the 'close' modifier and, for
completeness, to the the 'affinity' clause. – I think both are
relatively boring; possibly, with unified shared memory or (for
affinity) real NUMA memory, they become a tad more useful.
