Cache functions on create* for perfomance

[miyaji255]

Feature Request

Improves performance by caching functions when creating reusable functions (such as createValidate).

Simple Example

Current Generated Code:

(input: any): typia.IValidation<number> => {
  const errors = [] as any[];
  const __is = (input: any): input is number => {
    return "number" === typeof input;
  };
  if (false === __is(input)) {
    ...
  }
  const success = 0 === errors.length;
  return {
    success,
    errors,
    data: success ? input : undefined,
  } as any;
};

Suggesting Code:

(() => {
  const __is = (input: any): input is number => {
    return "number" === typeof input;
  };
  return (input: any): typia.IValidation<number> => {
    const errors = [] as any[];
    if (false === __is(input)) {
      ...
    }
    const success = 0 === errors.length;
    return {
      success,
      errors,
      data: success ? input : undefined,
    } as any;
  }
})()

Benchmark

I benchmarked createValidate with this interface.

interface IMember {
  id: string & tags.Format<"uuid">;
  name: string;
  age: number &
    tags.Type<"uint32"> &
    tags.Minimum<20> &
    tags.ExclusiveMaximum<100>;
}

Good idea, I'll try this way on weekend.

Performance be tuned significantly.
