* Update grammar * WIP with tracking classes - Refactor AvailableUserFunction to AvailableParseTree - Track ClassDeclarationContexts similarly to user functions * Skeleton AST + tracking * Finish up AST building * Implement AST building - TODO decide better name for UserFunctionBuilder/Visitor, since it does both user functions and classes * Update Prettifier * Crude, first-round semantic analysis + codegen - Currently, no real difference from regular functions * Move class var statements to top level statements * Add semantic analysis for base class existence * Introduce ClassInstance AST node for generating `this` parameter * Skeleton create class instance instruction * Default ctor; 'this' byref; Error if multiple same baseclass * Update grammar for scoped funcrefs and scoped identifiers * Update prettifier, builders for scoped funcref, identifiers * Fix CI issues - Styling - Shadowing * Add grammar tests for scope; Remove scope from switch label * Final draft todos - Rename `VarStatement::class_name` to `scope` - Comment why identifiers dont have scopes in enum declarations - Remove code comment
