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
