This can include constant expressions, macro de�nitions, and Nim procedures used by macro de�nitions. Most of the Nim language is supported at compile-time, but there are compile-time execution. Since constant expressions can be used as an input to semantic analysis (such as for de�ning array bounds), this �exibility requires the compiler to interleave semantic analysis and compile-time
