Thanks for your reply.
So writeln consumes the values in an InputRange. That leads me to
believe that if I feed an InputRange to foreach, it will consume the
values, too.
Did I get that right ?
Correct.
If that's the case, why I can iterate and write the values just fine
using nested foreach loops *and* writeln them afterwards ?
I would expect the foreach loops leaves "step3" in the same state as
writeln does.
So I'm still a little confused as to how foreach goes about it. I
thought foreach would be iterating an InputRange the same way writeln
does.
By attaching ".array" to the result of I was under the impression the
result was actually converted to an array.
That seems not to be the case. What I probably got was something like an
array of arrays of groups - which are apparently InputRanges ?
So, yes, writeln... InputRange... makes perfect sense except for the
foreach case.
Thanks again for the help :)
After playing around some more and apart from requiring much more
practice I think this topic can be marked as 'solved'. However, I can't
seem to find the edit button for my initial post.
Anyways, thanks for your contributions :) Very much appreciated!
Contrary to what it is called in the links, this is a NewsGroup/Mailing
