Hi there,
that is indeed very nice, for one has not to take care of the type
that is missing (up to now I skipped with null, which also works
if null is a valid default).
PS: Now that I am delving more and more into hansl, I also love it
more and more. It is really cool, (relatively) simple and very
powerful. So thanks for the great service you provide for people
like me!
Thanks! It's good to see someone "pushing the envelope" on hansl
usage. We'll see if we can improve matters in regard to some of the
points you have raised recently.
