$+x which expands to all arguments after and including argument x. Effectively this makes sar_alias obsolete but it's still nice to use it when you can.
?foo=bar shortcut for "var:foo=bar". Works around breakset so you need to quote fewer conds.
"<...>=var:bar" support. Very situational, reviewer's choice whether to drop or keep.
Similarly, <...>=?bar.
$# which expands to the number of arguments given. Not overly useful unless you're doing cursed config+++, but it's there now
$x can now expand to >9 arguments. The rationale for not doing this is laziness, but I'm not lazy... sometimes
