1. instance

   1. has events

      class Instance {
      	type: Type;
      	value: InstanceValue;
      }
      
      class InstanceValueImpl {
      
      	event_1(param_1, param_2) {
      	
      	}
      
      	event_2(param_1): returns {
      	
      	}
      
      	event_3(): returns {
      	
      	}
      
      }
      

2. type

   1. describes instances

      type Validator = (instance: Instance) => boolean;
      
      class Type {
      	allow: Validator;
      	deny: Validator;
      	strict: boolean;
      
      	validate(instance) {
      		let allow = 
      		if (this.strict)
      			return
      		return this.validator(instance);
      	}
      
      }
      

   2. validates instances

      
      number.validate(null); // false
      number.validate(number.resolve(null)); // false
      number.validate(number.resolve(10)); // true
      

   3. validates constraints

      
      let ten = number.allow((instance) => {
      	return (instance.value >= 0) && (instance.value < 10);
      });
      
      ten.validate(number.resolve(null)); // false
      ten.validate(number.resolve(-1)); // false
      ten.validate(number.resolve(0)); // true
      ten.validate(number.resolve(5)); // true
      ten.validate(number.resolve(10)); // false
