When I see all the various Scala compilers out there (Typesafe Scala compiler, LAMP/EPFL Dotty compiler, Scala.js, Scala Virtualized compiler, Scala.Meta system, and several research and private variants of the Scala compiler, IDEs own Scala variants) compared to the lone version of the Groovy one, I realize just how detrimental to the Groovy ecosystem was Codehaus Groovy's practise of ignoring creator James Strachan's JSR-241 standardization effort and redefining "Groovy" to mean the org.codehaus.groovy implementation only. At times it seemed they were scuttling others attempts to build a variant compiler, and even cannabalizing the annotation-based addon market like when they duplicated the Groovy++ static compilation "speed booster".
