Tell us about your environment

• eslint-plugin-typescript: 20.1.1

Please show your full configuration:

module.exports = {
  root: true,
  env: {
    browser: false,
    es6: true,
    node: false
  },
  extends: [
    'plugin:vue/essential',
    '@vue/standard'
  ],
  plugins: ['typescript'],
  parserOptions: {
    parser: 'typescript-eslint-parser',
    jsx: false
  }
}

What did you do? Please include the actual source code causing the issue.

function foo ({ v1, v2 }: { v1: number, v2: number }) {
}

What did you expect to happen?
year and month is not duplicated, its inline type definition

What actually happened? Please include the actual, raw output from ESLint.

Duplicate param 'v1'      no-dupe-args
Duplicate param 'v2'     no-dupe-args
'v1' is already defined   no-redeclare
'v2' is already defined  no-redeclare

looking at the version you said you're using (we are on 0.13) - it looks like you were using the latest version of the parser.

I am unable to reproduce this in master (parser v17).

issue is with parser not this plugin 👍
visitor-tree is not emitting it as type
