Parse error when "super" is used

[lukastaegert]

Originally via rollup/rollup#3505, which bundles this plugin at the moment:

It is not possible to use super in class properties even though it probably should, at least according to https://2ality.com/2019/07/public-class-fields.html#the-scope-of-field-initializers (I know this is not official documentation...)

At the moment the following throws with a SyntaxError: 'super' keyword outside a method:

require('acorn')
  .Parser.extend(require('acorn-class-fields'), require('acorn-static-class-features'))
  .parse('class SubClass extends SuperClass { prop = super.getValue(); }');

cc @guybedford Apparently I cannot create an issue in your fork

[pschroen]

I should add super works as expected in Chrome with the reference link example.

Tested with Version 81.0.4044.113.

Ok I've added a fix in guybedford@8a1fe76. Apparently I am now maintaining this :P No guarantees going forward.....

[adrianheine]

Fixed in #8.

[guybedford]

@adrianheine note that #8 was a different PR to the changes in guybedford@8a1fe76. If you would like me to turn that commit into a PR here I can do that though.

This issue should likely remain open until that is merged.

[adrianheine]

No, you pushed 8a1fe76 to that branch and I merged it.

[guybedford]

Ah great, I actually didn't even realise my fork branch and that PR branch were the same one.

Much appreciated for merging these fixes!
