- ... it doesn't matter (or it does ?) if op's are first
  instantiated via template, or everything is in one file
  and instantiated "per-need" when they appear (used).

  (tested various versions and cannot remember now)

- in any case: it should work in the separate-compilation
  model, with files split in *.hh, *.cc, *.ie
