Error recovery for letops

[anmonteiro]

Parser can't do automatic semicolon insertion (error recovery). Example:

Works:

let x = { 3; } // no semicolon, `refmt` can parse and insert it
let x = { 3; };

Doesn't work:

let+someOp x = { 3; } // no semicolon, `refmt` chokes
let x = { 3; };

The following does parse:

let x = {
  let+foo xx = { x }
  xx
};

while

  let+foo xx = { x };

does not (note the semicolon).

@anmonteiro I'm trying to reproduce this case - but failing to do so.

It might be outdated, but note that letops are expressions, not structure items

[anmonteiro]

can't repro the original example, but this one is reproducible:

let x = {
  let+someOp x = { 3; }
  and+someOp x = { 3; }
  ()
};
