Stuff regarding Go programming language.

• proper brace placement to avoid semicolon insertion
• “import path” versus “package name” (factored import statement)
• fmt.Printf() format specifiers
• named return values (explicit or allow to default)
• type “zero values”
• “var p = &Vertex{1,2}”, what is the scope/lifetime?
• how to list all package methods from the command line?
• how multi-platform things like Sqrt() work?
• possible formats of for loop
• neat uses of “defer” statements (stacked)
  • deferred call args are evaluated immediately
  • modifying named return values
• package “init” functions
• closures
• methods

• installation

• Go does not have classes; a method is a function with a special receiver argument (such as “Vertex”).
• Value receiver versus pointer receiver (one or the other, not both)
• Functions with a pointer argument must take a pointer, while methods with pointer receivers take either a value or a pointer as the receiver when they are called.
• Methods with value receivers take either a value or a pointer as the receiver when they are called.
