2.4.3. Sorry I should have said first time round. I will check the diffs to
the new version...
This "bug" is confusing the hell out of me. If I run the script with
groovyshell or groovyscriptengine or whatever it works, but if I add the
TypeChecked as a AST customiser then you get the result I posted above.
I would have thought it was the same code path.
Thanks for the info.
