lang: ast: improve cascade operator recipient resolution
...
the cascade operator now uses the precedence of the last message parsed
to determine the recipient of the subsequent messages, reducing the need
for parentheses and making the semantics of the operator more
predictable.
all messages in a cascade now inherit the precedence of the first
message in the cascade.
