totally agree with not use old java thing in go. but here we are trying to
solve a real problem.
i read your code, it make sense to me we need a interface to fib, so i
write such code (still i don't think your code can work with fib(n) n>1
since you did not use Recursive, when you use Recursive
You don't need to change the original function. Below, Fib(int) int is
the original function, and it illustrates two ways to decorate it.

Neither is a *bad* way to write code. Go is a different language so
some things you're used to in other languages must be
there is a way i can do the base, but we still change old function due
limit on go

you may say i can write a fib2 which have fib1+counter. but that is really
bad way to write code. and that's why we need decorator.

Hi, thanks for your answer, and i really cannot understander your code. can
you write a more clear version in go play ground?
i already create a template. pls notice that we cannot change origin fib
function.
