Regarding `end_of_expression` metadata

The docs state:

  • :end_of_expression - denotes when the end of expression effectively happens. Available for all expressions except the last one inside a __block__ (when :token_metadata is true)

My question is about “except the last one inside a __block__”.

Is limitation based on the existing parser implementation or is there an “actual” (in quotes because I’m not sure the right wording here haha) reason for the exception?

They are all expressions. The current docs state though that end_of_expression is added only to expressions with a __block__ (except the last one). The purpose of end_of_expression was to format blocks properly, which is why it is limited in scope. We could add it to all constructs in a block though. Adding them to everything is a taller order (and probably not that useful).
