## Message

```
fix std.fmt to handle std.SegmentedList

- add guards for use of prealloc_exp in SegmentedList
- define prealloc_exp even when invalid because std.fmt comptime
  triggers lazy-init
- fix std.fmt to print arrays of length 0 as style "[0]<typename>"
  because "<typename>@address" is n/a without address

```
