There was a problem hiding this comment.
This should be mod_spans.len() >= 2 or > 1.
Which is arguably why I'd consider the older version a little clearer in that regard.
instead of prefix `..`.
This breaks code that looked like:
match foo {

Change this code to:
match foo {
[ first, middle.., last ] => { ... }
}
RFC rust-lang#55.
Closes rust-lang#16967.
