types missing with --lib

[alexeagle]

I worked around #8091 by adding to the top of lib.webworker.d.ts

interface IDBIndexParameters {
    multiEntry?: boolean;
    unique?: boolean;
}
type IDBKeyPath = string;
interface IDBObjectStoreParameters {
    autoIncrement?: boolean;
    keyPath?: IDBKeyPath;
}

now I get another error:

TypeScript Version:

nightly (1.9.0-dev.20160409)

Code

$ npm install rxjs
$ cat tsconfig.json
{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "lib": ["webworker", "es6"],
        "noImplicitAny": false,
        "sourceMap": false
    },
    "exclude": [
        "node_modules"
    ],
    "files": ["repro.ts"]
}
$ cat repro.ts
import * as o from 'rxjs/observable/FromEventObservable';

node_modules/rxjs/observable/FromEventObservable.d.ts(11,104): error TS2304: Cannot find name 'NodeList'.
node_modules/rxjs/observable/FromEventObservable.d.ts(11,115): error TS2304: Cannot find name 'HTMLCollection'.

do not think HTMLCollection or NodeList are available for webworkers. webworkers should not have access to the dom.

webworkers was a red herring here, I can also repro with:

$cat repro.ts
import * as o from 'rxjs/observable/FromEventObservable';
$cat tsconfig.json
{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "lib": ["es6"],
        "noImplicitAny": false,
        "sourceMap": false
    },
    "exclude": [
        "node_modules"
    ],
    "files": ["repro.ts"]
}
$./node_modules/.bin/tsc
node_modules/rxjs/observable/FromEventObservable.d.ts(11,39): error TS2304: Cannot find name 'EventTarget'.
node_modules/rxjs/observable/FromEventObservable.d.ts(11,104): error TS2304: Cannot find name 'NodeList'.
node_modules/rxjs/observable/FromEventObservable.d.ts(11,115): error TS2304: Cannot find name 'HTMLCollection'.

oh, I see, I need lib: ["es6", "dom"]

This is a problem in angular2 compilation, where we currently compile code that's meant to run in a webworker in the same compilation unit with code that runs in browser, so I would need all the types from

lib: ["es6", "dom", "webworker"]
but that gives lots of TS2300 Duplicate identifier errors.

It's too bad that any code depending on angular2 has to typecheck the angular2 .d.ts files, as they contain a mix of webworker and browser code. I can compile with --target=es6 but as soon as I change to --target=es5 there seems to be no value for the --lib flag that makes the typechecking succeed again.

Actually, now I cannot reproduce a need for both dom and webworker. Maybe the workaround for #8091 actually solved all my problems.
