@full-kilobyte-93429 and maybe @witty-crayon-22786: We have upgraded to 0.0.59 and (probably unrelatedly) have gotten reports of ‘Argument too long’ in the scala repl. Have you done any experiments with turning on the synthetic jar in the repl? I trivially turned it on, but I see classloader issues and am wondering if you tried this and gave up for reasons.
