Hi Guillaume, === and !=== are available for Groovy 3, so "!is" is not necessary.
Currently only "!in" and "!instanceof" are supported with sticky style: https://github.com/danielsun1106/groovy-parser/commit/69023a63446d14add54f43d3d7797c9dd2a7f903 If it is ok, I'll merge it into parrot branch of apache/groovy.
