i had a port of it a month ago, but iirc it crashed straight away on the first perl files i gave it (two different versions of kpcli source file). Have you tested it extensively with various file types?
I tested it with elm, haskell, javascript, json, c, and just right now with infrastructure/dpb - I wouldn't claim that this qualifies as 'extensive', but I didn't see any crashes so far. Also the included tests pass without a single failure.
If you send me the two files that crashed it, I'll also test with them.
