Several compiled into the executable. However, some code may be executed at compile-time. This can include constant expressions, macro de�nitions, and Nim procedures used by macro de�nitions. Most of the Nim language disabled. A constant expression is an expression whose value can be computed during a semantic analysis of the code in which it appears. It is never an l-value and never has side effects. Constant expressions

Constants Constants in Go are just that—constant. They are created at compile time, even when defined as locals in functions, and can only be numbers compile-time restriction, the expressions that define them must be constant expressions, evaluatable by the compiler. For instance, 1<<3 is a constant expression, while math.Sin(math.Pi/4) is not because the function
