Syntax: A Casual and Formal Look

Call Syntax

First, a word on the distinction between expressions and statements. Expressions return a value. Statements do not. That is all.

There are some syntactic constructs unambiguously recognizable as statements: all declarations, modules, and use statements. There are no syntactic constructs unambiguously recognizable as expressions. As calls returning void are treated as statements, and expressions that return a type could possibly return void, there is no explicit distinction between expressions and statements made in the parser: or anywhere before type-checking.

Expressions can go almost anywhere. Our indentation rules above allow for it.
