Just ran into this, which I wasn't expecting:
> DB[:table].freeze == DB[:table]
=> false
This is because the frozen state is stored in the opts hash, and Dataset#==
compares the opts hashes. This might seem reasonable, but it clashes with
Ruby's behavior more generally:
> "string".freeze == "string"
=> true
> [].freeze == []
=> true
> {}.freeze == {}
=> true
Not sure if this should be changed or not, and even if everyone agrees it
should, some people might rely on the old behavior. Maybe something to
revisit in the next major version?
