   This isn't the complete solution. It enables the test suite to pass and supports numerous forms of Groovy 3 syntax that I tried in an exploratory fashion. It is known to be deficient in terms of completion, e.g. !instanceof/!in infix operators don't have auto-completion whereas in/instanceof do and possibly others. There are possibly additional cases which need to be handled to support the multi-line "approach" (hack?) which groovysh uses. The old parser is obtainable in the usual way, e.g. set JAVA_OPTS=-Dparser.antlr4=false
