[jira] [Comment Edited] (GROOVY-6871) Running :show all command throws StackOverflowError
[ https://issues.apache.org/jira/browse/GROOVY-6871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17561996#comment-17561996 ]

We haven't progressed detecting printing mutually recursive structures yet. I implemented a workaround for this case in the meantime. It simply avoids including the '\_' value in the variables returned by {{:show all}} and substitutes a '\_' placeholder instead as shown here:
{noformat}
Groovy Shell (5.0.0-SNAPSHOT, JVM: 17.0.2)
Type ':help' or ':h' for help.
