Examples should be clear when they are using built-in functionality vs. library

[domenic]

A lot of examples seem to use functions like limit, createServer, debounce, or until. It is unclear which of these are part of the proposal.

Examples that use things that are not part of the proposal can be misleading in that they make it seem like the proposal gives us capabilities it does not, or makes things easier with emitters when in reality when you use a library you can make any paradigm easy.
