[0.15.0] const enums are not being exported anymore

monaco-editor version: 0.15.0

With the new 0.15.0 release, export const enum ... are not getting exported in the standaloneEditor anymore. As an example, paste this code to the playground:

require(['vs/base/common/scrollable'], ({ ScrollbarVisibility }) => {
    if (!ScrollbarVisibility) alert('ScrollbarVisibility has not been exported :(');
});

Looking at the sources, ScrollbarVisibility should get exported correctly: https://github.com/Microsoft/vscode/blob/master/src/vs/base/common/scrollable.ts

Reading the history of that file, it looks like the changes made in this commit are causing the problem: https://github.com/Microsoft/vscode/commit/67eacaa4a856be0b90435c71de1996a12ff02f61#diff-c4d985a76a54961df57cff1260208b54

Fair enough 😅Thanks for looking into this.

I am sorry, but I would not accept such a PR.

I do not want our code to pay the cost at runtime of evaluating:

var Test;
(function (Test) {
    Test[Test["Hello"] = 1] = "Hello";
    Test[Test["World"] = 2] = "World";
})(Test = exports.Test || (exports.Test = {}));

for no good reason.

You are reaching into the editor internal implementation and you cannot complain when that changes or breaks. That is how libraries work, internal stuff can break or disappear at any time. We try as best we can to maintain our API surface in a backwards compatible way.
