I believe currently the first field in the record behaves slightly differently from the rest:

let long_variable_name =
  { xxx = 1;
    yyy = 2;
    zzz = 3 }
in

Would it be possible to support a style where all fields get the same indentation? For example,

let long_variable_name =
  {
    xxx = 1;
    yyy = 2;
    zzz = 3
  }
in

Or a docked varaint (which I believe is already supported for record type declarations):

let long_variable_name = {
    xxx = 1;
    yyy = 2;
    zzz = 3
  }
in
