Try-catch-finally not supported?

Hi!

Not sure if this is a bug or really not supported by nextflow but I get errors from the checker when using try-catch-finally. In my case in the workflow.onComplete block

Unexpected input: 'finally'

I didn't include finally in the strict syntax because I wasn't sure if it would be needed. I'm open to supporting it, it's not a big deal, but I wonder if there is a way to do what you want without a finally clause. I don't think the disconnect() is strictly needed here

Hmm yeah I can't judge. I agree that it might not be absolutely necessary here, although nice-to-have.
I guess if it does not interfere with anything that could break a flow it would not hurt supporting it.
This was my first need for a finally.
