Now, there aren't actually docs for Transposed, but you can
find it if you look at std.range.transposed:
Thanks, I had found that but that is not an explanation unless
you have a lot of prior technical understanding of what save is
and why it's not working. I guess it's a general doc quality
issue - unless you're already very knowledgeable it's pretty much
useless to understand the problem you have.
I transposed a range of ranges to pass to a function to get the
distance between characters in strings. That works fine, as does
printing the result. But it then complains if I try to do
anything like fold with the result.
