Thanks, that solves the problem perfectly well!

Isn't this only the case for AOT compiled deftype? F
Sorry, I think my reply got lost...
Inside deftype methods the symbol "Bar" is the name of the class. You
can use the constructor (Bar. (inc i)) instead. Again, note the "."
after Bar.

That's probably the cleanest solution, but you lose the performance
benefit of defining methods right in the type defini

I want to create a new instance of a deftype from inside one of its
methods. A basic example would be
(defprotocol Foo
(foo [x]))
(deftype Bar
[i]
Foo
(foo [] (Bar (inc i
(foo (Bar 0))
This fails with an exception:
java.lang.ClassCastException: java.lang.Class cannot be cast
