Decorators on accessor private fields report SyntaxError

[weareoutman]

Prettier 2.8.5
Playground link

--parser typescript

Input:

class A {
  @dec() accessor #field;
}

Output:

SyntaxError: Decorators are not valid here. (2:3)
  1 | class A {
> 2 |   @dec() accessor #field;
    |   ^^^^^^
  3 | }

Expected behavior:

No SyntaxError. Change the parser from "typescript" to "babel-ts" will make it work.

Prettier 2.8.4 works fine, seems 2.8.5 introduced this.

TypeScript seems don't allow it playground

You should unset the experimentalDecorators option. While it's enabled, it uses stage 2 decorator proposal, not the latest stage 3 proposal

Thanks for reporting this issue, I'll release a fix once #14548 passes tests.
