Adding multiple fields to a record

[nphollon]

Elm allows us to update multiple fields at once on a record. By analogy, it feels very natural to add multiple fields using this notation:

addTwoFields record = { record | b = 4, c = 7 }

But it leads to a syntax error:

Parse error at (line 8, column 39):
unexpected ","
expecting digit, ".", "e", "E", whitespace, a newline, "-", basic term (4, x, 'c', etc.), infix operator or closing bracket '}'

The alternative I have found is rather verbose:

addTwoFields record = 
  let record' = { record | b = 4 }
  in { record' | c = 7 }

My apologies, this issue looks like it belongs in elm-compiler, not in core
