"There is one exception to this rule: two variables whose type carries no information and is therefore of size zero, such as struct{} or [0]int, may, depending on the implementation, have the same address."
"It is not a problem if the map doesn't yet contain that key"
"if the expression is omitted, the initial value is the zero value for this type"
"It perfectly safe for a function to return the address of a local variable"
"Any file may contain any number of functions whose declaration is just func init() {}"
"The type rune is an synonym for int32"
"The compiler represents these uncommitted constants with much greater numeric precision than values of basic types, and arithmetic on them is more precise than machine arithmetic; you may assume at least 256 bits of precision."
