A "DSL" like SQL that you use hundreds of times a year you'll learn the model of.

A DSL like groovy that you use once for project setup (and for that you'll one-off it likely and stackoverflow the rest of the question) is not. And it isn't really natural, it's a bunch of arcane steps that at the end might superficially look a bit consistent, but still really isn't.

Groovy really needs an autocompleter or a generator. Or, well, as you say, you stackoverflow for everything outside the very vanilla basics of it.

But good luck getting the right version match to the syntax you need. Christ.
