IMHO at least, this should be an error. As a side note I do think that try
should have greater precedence than as, even though this does potentially limit
calls that would use only one try on a series of throwing statement that can be
handled using parentheses. The benefit is that try is probably called in the
vast majority of situations (that’s my experience at least) on a single throw
statement and having it have higher precedance would avoid some surprises as
most developers probably already assume that try wil be executed before as.
