Enums are not handled in the proto compiler

[evanw]

Maybe I'm missing something, but I can't get enums to work:

$ cat > example.proto
package figma;

enum ExampleType {
  A = 0;
  B = 1;
}

message Example {
  required ExampleType type = 1;
}
$ ./bin/pbf example.proto > example.js
$ node -e 'pbf = require("./index"), console.log(require("./example").Example.write({type: "A"}, new pbf()))'
pbf/example.js:16
    if (example.type !== undefined) pbf.writeMessage(1, writeExampleType, exam
                                                        ^
ReferenceError: writeExampleType is not defined
    at Object.writeExample [as write] (pbf/example.js:16:57)
    at [eval]:1:68
    at Object.exports.runInThisContext (vm.js:74:17)
    at Object.<anonymous> ([eval]-wrapper:6:22)

    at evalScript (node.js:431:25)

It looks like there's code that should be handling enums, it's just never being called.

Ha, turns out it handles enums properly if they're nested inside a message, but not when they're defined in the root. Looking into this.
