Well, it would work. It's just that it felt like such a big hack that I
didn't want to touch it at first. In general if one adds one thing like
this after another, we end up like some other database with lots of
strange ugly features.

It doesn't have to be very hard to parse it. One can just parse it as an
expression and have a transformation phase that checks if the expression
is a top level "=>" with a single identifier to the left. If it is we
transform it to named argument. Probably one also need to record if the
top level expression is in () and set a flag to not trigger the above
logic.
