Add a files method

[brson]

Like file but takes multiple files. Make it accept IntoIterator<Item = AsRef<&str>>.

@brson maybe IntoIterator<Item = AsRef<Path>>? file takes AsRef<Path>.

[alexcrichton]

@opilar yeah that sounds right to me!

[opilar]

Can anyone help me with that?

Oh that's actually shorthand, I think what you'll actually want is:

fn files<P>(...)
    where P: IntoIterator, P::Item: AsRef<Path>
