RUST-836
This adds support for the 'let' option to
aggregate
. Unfortunately,let
is a reserved keyword in Rust, so this PR implements it aslet_vars
.r#let
would have worked as well, but that's awkward and unidiomatic (typically raw identifiers are only used for edition compatibility), and could also have caused confusion, as the debug format prints it as just "let".
