Follow-up Comment #1:
It is definitely supposed to create only one subclass - classes are generally
generated at compile-time (or load-time if you think of the actual Class
object, not during execution.
The problem is how 'map' is inlined to a loop. The bug is that there is only
one variable for 'prefix', and each instance shares the same 'prefix'.
Here is a work-around:
(let ((v (map (lambda (prefix0)
(object (java.lang.Object)
(prefix prefix0)
((my-method value) (string-append prefix "-" (number->string
value)))))
(list "ALPHA" "BETA" "GAMMA"))))
....
New bugs should probably be reported on the gitlab bug-tracker.
