+1. The other way would also (presumably) mean invoking the language's
validate procedure, which might well be redundant and in any case would
probably not have exactly the error-reporting behavior one would want.
I think it's better if the language knows it's dealing with an anonymous
block. You could even imagine the language relaxing its rules a bit,
for instance not requiring an outer BEGIN/END in plpgsql.
