Ouch. I guess this would be a reason to use strings more, since they're immutable.

[morelisp → skybrian]

Someone using a string when they really want a byte array/slice would fail review on its face. Excepting external APIs forcing "strings" on us, we only use the Go string type for UTF-8 code unit sequences (and this is a common assumption in the Go world).

Using string doesn't allow reuse, so you are leaving significant performance on the table.
