Originally created by @mitchcapper on GitHub (Feb 21, 2024).

Tells me its an unexpected error. Simple pkl file:

import "pkl:reflect"
a = reflect.Class( 5.getClass() )

I assume you don't need the entire stack trace on this one but if you want it let me know

jpkl eval test3.pkl

Marking as fixed, because #170 is in the past. If you run into this again on the snapshot builds or future releases, please re-open.

Is there a public circleci or snapshot builds somewhere? Given #20 cannot quickly local compile to test.
