Changes in the standard that we need to adopt

"3.8.3. new ReadableStreamDefaultController" and "3.10.3 new ReadableByteStreamController" should always throw a TypeError now. Controller setup is done in "3.9.11. SetUpReadableStreamDefaultController".

Our CreateReadableByteStreamController() is also questionable.
3.8.4.2 has changed; ReadableStreamDefaultControllerCanCloseOrEnqueue

Real-world testing for readable streams

The goal of this testing project is to:

Find existing web sites that actually do use streams in Firefox Nightly (when streams are enabled);
Test the user experience with those sites and report any bugs or performance problems.

(We already have API-level tests for streams that run in automation, so we are not requesting new automated tests that exercise the streams API directly.)

Author Notes: This recipe is served as a starter to each dinner table at Kindred Restaurant in Davidson, North Carolina. But the dough doesn't stop there. It can be used as sandwich bread, French toast, burger buns, doughnuts, and more. This is a bread that merges utility and taste, seamlessly. —catherine margaret o'donnell

Makes: 6 rolls, two 9- by 5-inch loaves, or 12 split-top buns
Prep time: 2 hrs
Cook time: 1 hrs

5 1/3 cups bread flour, divided, plus more for surface (Kindred uses King Arthur)
1 cup heavy cream
1/3 cup mild honey (such as wildflower or alfalfa)
3 tablespoons nonfat dry milk powder (such as Alba)

Anomalies in mainstream programming language grammar: an incomplete freak show

Parser generators have existed forever. Why don't any serious compilers use them?

Well, Python uses one... written from scratch to parse Python, unsuitable for any other project.

One reason is that programming languages are such amazing trash. The more widely used a language is, the more likely it is
