Thread:User talk:CodeCat/Is there a Lua sandbox or equivalent on Wiktionary?

There's Module:Sandbox on WP to allow you to try out Lua modules before putting them in the main namespace. Is there any equivalent in Wiktionary? I created Module:fro-verb and so far I've been editing and testing it in-place, which necessarily means that I sometimes commit bugs. I'm thinking of expanding it a lot and I'd rather do the testing elsewhere.
