[14:41:04] observation: GF goes crazy if doing "case foo of { bar => case foo of { … } ; baz => … }" [14:41:20] the trick is that the second "case foo" may be in a different function [14:43:13] so case foo of { bar => analyseFooFurther foo 10 "your mom" ; baz => … } [15:27:52] nevermind, it must've been something else, can't reproduce a minimal example [15:28:07] that was anyway the step that fixed the original problem :-P
