There is an old thread about this, where Daan suggested "unchecked"
instead of "unsafe".
"unsafe" reminds to "IO" stuff.
Didn't you read the comment about fromAscList? Isn't the name long
enough to scare you?
Would you have not taken "unsafeFromAscList" under the same
circumstances you've chosen "fromAscList"?
