Prefer implicit return on fat arrow if possible

[dan1elhughes]

Hi, is there an option for replacing immediately-returning fat arrow functions with implicit returns?

Prettier 1.14.0
Playground link

# Options (if any):
--single-quote

Input:

module.exports.collect = (val, memo = []) => {
  return [...memo, val];
};

Output:

module.exports.collect = (val, memo = []) => {
  return [...memo, val];
};

Expected behavior:

module.exports.collect = (val, memo = []) => [...memo, val];

Hi, this is one of our non-goals since it affects the AST, we recommend you to use fixable linter rules (e.g. arrow-body-style) to achieve it.

OK cool, thank you!
