ahem ... ditto (well, just mostly out of "net" in my case) :-)

Yes, and a special pseudo-technique "+" for "repeat"

I wasn't thinking of yet another option, but rather a special
technique-name, such as "^"
so, "^,ns,hs,+" would then repeatedly try all techniques
except the naked and hidden single... (just for example;
I don't see any particular reason to exclude these two)
The ^ would only be recognized as first technique, and
anything following the "+" could be an error (but need not)

PS:
Just yesterday I noticed the first wrong outset in some
sudoku-booklet, myself - it had two solutions.
