Highlights
* compile one module at a time
* use summaries to speed up compiles
* use command runner so we can add more commands later
* some long needed renames and file organization
* various other technical debt has been addressed
Lowlights
* lost node.js runner/tests (node output format still supported)
* possibly lost some closure support/workarounds (format still supported)
* needs more end-to-end tests of the new system

- Replaced ClosureType by a general JS.TypeRef, used in AST for identifier types, return types
- Convert DartType to JS.TypeRef (in mixin JsTypeRefCodegen), including type parameters (also added to AST in Fun & ClassExpression)
- Emit field declarations expected by TS
- Wrote a TypeScriptTypePrinter (mixed in by Printer) and a ClosureTypePrinter (might disappear soon)
- Simplified annotation code, called in more places (seems to gives more source info)
Example input:
List/*<T>*/ func/*<T>*/(List/*<T>*/ items, dynamic/*=T*/ seed) {}
class Foo<T> {
int i;
static var x;
Foo(this.i, o, {String v : "?"}) {}
}
Output:
function func<T>(items: core.List<T>, seed: T): core.List<T> {}
const Foo$ = dart.generic(function(T) {
class Foo<T> extends core.Object {
i: number;
static x;
Foo(i: number, o, {v = "?"}: {v?: string} = {}) {
this.i = i;
}
}
...
Foo.x = null;
return Foo;
});
Known remaining issues:
- typedefs expect a `type Callback = (...) => ...;` statement
- `exports` is a reserved keyword in TS (either we change the way we do exports, or we'll need a different temp + extra type annotations of the default-exported object).
- Generic type is currently locked inside the generic call. Might be able to solve by exporting signatures in .d.ts file, or changing the way we do generics.

function f(a, opts) {
let b = opts && 'b' in opts ? opts.b : null;
let c = opts && 'c' in opts ? opts.c : c_default;
...
After:
function f(a, {b = null, c = c_default} = {}) {
...
Note:
- Still reverting to old code when any parameter clashes with reserved JS names (see discussion in https://github.com/dart-lang/dev_compiler/issues/392)
- When a parameter clashes with a Object.prototype property, using a clean default opts value (Object.create(null)).
- Passing opts through in aliased constructors, both for speed/concision and correctness (since default param value semantic is weird there)
