Not my project, but I'll ping it over to Dmitry. One thing is that it's possible that Ellx uses exceptions to detect time series and lift regular functions into time series functions. I'm not sure the implementation details. There are all kinds of ways exceptions can be abused to implement near-magic. (I believe there's a library that uses exceptions in OCaml to implement coroutines.) I wouldn't be surprised if Ellx used some try-catch near-magic that doesn't quite work on Safari.
