Should `|`ed match arms be indented?

[nrc]

For consistency with other binops?

E.g.,

Foo
    | Bar
    | Baz

rather than

Foo
| Bar
| Baz

I don't recall discussing this, but maybe we did.

I think we'd just have to always use { in the match arm and put it on a newline to make things stand out.

I thought that we did and decided on the latter. Personally, I prefer the latter over the former; I think | provides enough visual distinction of continuation lines.
