let in select has a bad error

[Licenser]

when we have a let in select we should print a nicer error

The current error is:

Error: 
    6 | 
    7 | select 
    8 | let a = event.foo;
      | ^^^ Found the token `let` but expected one of `!`, `\``, `$`, `(`, `+`, `-`, `<ident>`, `[`, `absent`, `args`, `bool`, `event`, `float`, `for`, `group`, `heredoc`, `int`, `match`, `merge`, `nil`, `not`, `patch`, `present`, `recur`, `state`, `window`, `{`
      |     NOTE: Did you mean to use `!`?
    9 | from in into out;
   10 | # select event from foo/err into out/err;

Is this the bad error reported here? Or can we consider this issue fixed?
