- Auto-register func Type_Method<T>(self: *Type<T>) as methods in sema - Add type param awareness to sema resolveType for generic function bodies - Add lazy monomorphization for generic struct method calls in HIR lowering - Track varTypeExprs in LowerCtx for local variable type inference - Fix ekSelf in both sema and hir_lower to resolve actual parameter type - Fix lowerFunc to use substituteType for param/return types (handles pointers to generic structs) - Auto-address value receivers when method expects pointer (e.g., b.Get() where self: *Box<T>) - Add C forward declarations for all functions to fix ordering issues - Relax type checks for tkTypeParam in assignments and arguments - Update generics_struct example with Box_Get, Box_Set, Pair_GetFirst/Second
