"Dynamic" Types

Tuple

C++: 100+ LOC?

Birdee:

class tuple[T... as class]
	{@
		i=0
		for type in T:
			class_body(f"public v{i} as {type}")
	@}
end

tuple[int,long] is

class tuple
	public v0 as int
	public v1 as int
end

Auto code generation

Object to JSON?

C++: hard/ugly - invasive solutions

Java: runtime reflection - overhead

Birdee:

function obj2json[T](obj as T) as string
	dim js as json=new json
	{@
		for field in T.fields:
			expr(f"js.add_key_value('{field.name}',obj.{field.name})")
	@}
	return js.getstring()
end

Getter/Setters?

{{
	#python function
	#generates getter/setters for each private fields 
	def gen_get_set():
		selfclass=get_current_class()
		for field in selfclass.fields:
			type=field.type
			if field.access==AccessModifier.PRIVATE:
				class_body(f'''
					public function get_{field}() as {type}
						return {field}
					end
					public function set_{field}(f as {type})
						{field}=f
					end				
				''')
}}

class SomeDataClass
	private a as int
	private b as string
	#I have 100 fields
	{{
		gen_get_set() ##auto generate getters & setters
	}}
end

DAO

C++: ???

Java: annotation, reflection - overhead

Birdee: ...
