tsc vs babel on enum transformation

[branchseer]

oxc-transform currently follows babel's rules on enum transformation. IMHO it's a little bit weird about whether an identifier should be resolved to the enum member:

playground link

(() => {
  var A = 'hello';
  enum Foo {
    A = 1,
    B = A, // A is resolved to the enum member if it's constant
  }
})();

(() => {
  var A = 'hello';
  enum Bar {
    A = Math.random(),
    B = A, // Otherwise, A to resolved to the outer scope's binding
  }
})();


enum Baz {
  A = Math.random(),
  B = A, // If there's no outer scope's binding, it's again resolved to the enum member
}

In contrast, tsc has a simpler rule:

playground link

// A is always resolved to the enum member.

(() => {
  var A = 'global';
  enum Foo {
    A = 1,
    B = A, 
  }
})();

(() => {
  var A = 'global';
  enum Bar {
    A = Math.random(),
    B = A,
  }
})();


enum Baz {
  A = Math.random(),
  B = A,
}

Would it be better to switch to tsc's rule? I'd love to draft a PR if it's preferred.
