Hans, thanks for the reply
(3) the good news is that you can do this:

Ooh that is news:-) (the luatex manual doesn't seem to mention a
possibility of class here)
it's sort of an experiment ... which will probably stay ... so it can be
revealed ...
but why 5 (closing)? I'd have expected to specify 3 (relation) to get
these are internal classes which have more granularity
0 ord
1 op normal
2 op limits
3 op no limits
4 bin
5 rel
6 open
7 close
8 punct
9 inner
10 under
11 over
12 vcenter
symmetric spacing but that gives thinmuspace not thickmuspace (at
least with luatex 1.04 as distributed with texlive)
