[alexbit-codemod]

1. successfully installed the playground.
2. put the before and after code from the doc here: https://github.com/uber/piranha/tree/master/experimental in the relevant boxes
3. clicked on infer rules from templates. got some rule inferred.
4. clicked Apply rule to before and got the following error in the code after section

seems that the inferred rule has some syntax issues.

[alexbit-codemod]

strangely enough, even though the code is in java, when i switch the picker in playground to kotlin and try to infer rule again, i can actually apply the inferred rules and get the correct result!
it just says "Produced syntactically incorrect source code" but it is actually corret. @ketkarameya

The problem is the new lines in 15 through 17 (#eq? tag8n …). The static inference algorithm is not that smart, I’ll fix it.

I assume it’s saying incorrect source code because the Kotlin parser is unable to parse the code
