Failure on `static` method name

Came across this in ncc here - vercel/ncc#438.

fast-glob contains something along these lines:

class C {
  static () {
  }
}

Which is throwing a parser error when this plugin is applied.

error while parsing static get = 1

'use strict';

Error.stackTraceLimit = 100;

const parser = require('acorn').Parser.extend(require('acorn-stage3'));

parser.parse(` class a { static 'get' = 1; } `);// avoid error

parser.parse(` class a { static get = 1; } `);// error but valid in fact

Parse error when "super" is used in a static class field

Originally via rollup/rollup#3702:

At the moment, the following example throws with "'super' keyword outside a method" when parsed:

class Foo extends Bar {
  static field = super.field + 1;
}

This should be supported and actually runs fine in e.g. current Chrome.

Here's a Stackblitz repo on @Josh-Cena's great repro: https://stackblitz.com/edit/stackblitz-starters-zw7gm8?file=index.js

          Here's a Stackblitz repo on @Josh-Cena's great repro: https://stackblitz.com/edit/stackblitz-starters-zw7gm8?file=index.js

Just run node index.js and see the error. Try downgrading to [email protected] and see it run fine.
