Declarations

Use declaration

This declaration starts with the keyword use.

use_decl := 'use' IDENTIFIER | STRING ('as' STRING)?

After the keyword, we allow an identifier or a string as a module name. And optional as postfix makes alias.

Var declaration

This declaration starts with the keyword var.

var_decl := 'var' IDENTIFIER ('=' expr)?

The identifier becomes the name of variable. If = follows behind, we have an initializer value.

Class declaration

// todo

Func declaration
