I guess extend-type does changes only to generated java class and the var
defrecordissue.arecord->ARecord
contains the 'old' version of ARecord constructor. Obviously it would be
weird for defprotocol to change the variable in another namespace.
Especially when you can extend a record from anywhere.
So If you want to create a record that implements your protocol via var
from record namespace, you should do some hackery to update that variable.
I've done a pull-request for you, but using direct constructor will be more
idiomatic
