- Add ekGenericCall to AST for generic function calls (Max<int>)
- Parse generic type arguments in parsePostfix
- Support generic calls in sema with type parameter substitution
- Implement monomorphization in hir_lower:
- Collect generic function declarations
- Find all generic call sites
- Generate specialized versions with mangled names (Max_int)
- Substitute type parameters with concrete types
- Add generics.bux example
Example:
func Max<T>(a: T, b: T) -> T {
if a > b { return a; }
else { return b; }
}
let m: int = Max<int>(10, 20); // Generates Max_int
