Example
for is the only loop statement in go, so a basic loop implementation could look like this:
// like if, for doesn't use parens either.
// variables declared in for and if are local to their scope.
for x := 0; x < 3; x++ { // ++ is a statement.
fmt.Println("iteration", x)
}
// would print:
// iteration 0
// iteration 1
// iteration 2
