3 years ago Absolutely on our to-do list. A prerequisite is adding a type system and asymmetric types (so we can have an error type), errors/error handling would be a good first take on that.
It might be worth looking to implement something along the lines of rusts Result / Option type and the ? operator which is a really neat functionality halfway through always explicit and never explicit handling of errors.
Describe the problem you are trying to solve At the moment, Tremor Script does not feature a way to "catch" and respond to runtime errors/exceptions.
Describe the solution you'd like Try-Catch is already a familiar construct in many other languages, so an in-depth explanation probably isn't needed here. The gist of it is being able to execute some Tremor Script statement that has some potential to fail, and wrapping it in a block of Tremor Script that can respond to that failure in a specific way. This would be particularly helpful when dealing with blocks of Tremor Script that attempt to parse, cast, or coerce a field's value.
