I rather like
let { binding and binding and binding in EXPR}
or let binding
binding
binding
in EXPR
This leaves no question in the reader's mind about the scope of the
variables. It is explicit that all variables share the same scope, which is
the intent here, isn't it?
If you want nested levels of scope, then put another let block in the EXPR.
This is basically Haskell syntax, perhaps I'm already showing by bias.

We can't solve problems by using the same kind of thinking we used when we
created them.
