Introduce a notion of a "node matcher" which abstacts knowledge of how to match certain kinds of nullability nodes. This significantly simplifies the tests of substitution nodes; instead of digging through the graph to find the substitution node, asserting that it is a substitution node, and then asserting that it has the right form, we can simply use the existing `assertEdge` method to assert that an edge exists with the appropriate kind of substitution node as either its source or destination.

Dart
A client-optimized language for fast apps on any platform
Dart is:
-
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app
-
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web
Dart has flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
-
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
-
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
