Suggestions for additional running modes

[Lucretiel]

• Combined --loop and --expr, where the lambda is evaluated once per line, and the return value is printed
• Related to the above, --loop --flatten, which is the same as above, but the lambda returns an IntoIterator (such as Option<T>) and prints each item once per line
• --display mode, where Display is used instead of Debug when running in expression mode to print items

--display mode, where Display is used instead of Debug when running in expression mode to print items

Perhaps Display should be the default, and Debug opt-in? What do you think?

[Lucretiel]

Oh, I definitely agree with that. I was only suggesting --display in the interest of backwards compatibility; I definitely thing Display should be the default and Debug can be opted in to.

Can we have an offline mode? There is a related issue at cargo-script
