in thread way of declare an integer variable instead use /^\d+$/

Tie::Scalar whatever it can do,it's overkill to declare an integer, I do not know how to implement it, I seldom use class in my scripts.

It may be either-or, I can not have both, regex is a much general define method, I'm learning to appreciate it, since 'every perl script use regex'
