Miscellaneous

• Using channels to monitor the amount of time a program is running and time it out, signals: "Go in Action" Section 7.1 Runner (page 179), playground/go/go-in-action/runner
• Pooling "Go in Action" Section 7.2 page 188
• Workers "Go in Action" Section 7.3 page 198

Conventions and Idioms

• Name factory functions New. The factory functions should return a value or a pointer depending on the primitive nature of the type.
