TypeScript complains about overwriting .d.ts files that are potentially known outputs

See original GitHub issue

Using tsc at the command line, I got

error TS5055: Cannot write file '/Users/alexamil/WebstormProjects/oresoftware/ldap-pool/index.d.ts' because it would overwrite input file.

why? 😃

my tsconfig.json file is as follows

{
  "compilerOptions": {
    "declaration": true,
    "baseUrl": ".",
    "types": [
      "node"
    ],
    "typeRoots": [
      "node_modules/@types"
    ],
    "target": "es5",
    "module": "commonjs",
    "noImplicitAny": true,
    "removeComments": true,
    "allowUnreachableCode": true,
    "lib": [
      "es2015",
      "es2016",
      "es2017"
    ]
  },
  "compileOnSave": false,
  "exclude": [
    "node_modules"
  ]
}

At the very least there should be a flag that allows you to force an overwrite.
