Detailed Description

Statements make up most things in source code.

This includes declarations (such as function declarations) which must be at the top level of a program; or things such as if statements, which must be inside the bodies of functions, but have no associated value. Expressions (Expr) are subclasses of Stmt, but do have an associated value. Note that in a future version of the language, declarations could be moved to a separate class and the distinction between statements and expressions may be removed.
