Paul King resolved GROOVY-6871.
-------------------------------
Fix Version/s: 5.0.0-alpha-1
4.0.4
Assignee: Paul King
Resolution: Fixed
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}} as shown
here:
{noformat}
Groovy Shell (5.0.0-SNAPSHOT, JVM: 17.0.2)
Type ':help' or ':h' for help.
