he he, I have always considered myself one of the "OO-minds", which
is the reason for me screaming "hack hack hack!" at the beginning.
But we are discuss a different issue from the OP, which is, again,
undeniably, hack, hack, hack! 8-)
My point is that, from (exactly) the OO point of view, a specific
Method object should represent the specific version of the method,
because this Method object is obtained from one specific Class object,
which is abstractly a specific version of the interface. |

I agree with you all the way - until the part after "for ..." 8-)
Again, when you get to a specific Method object, it represents
a specific version.
Exactly, every one of all these differences is a reason why
when I invoke on a specific Method object, I want that specific
version of the method to be invoked.
True, but that should be and can be easily enforced by run-time

for histone, there is no specific binding site on DNA. But histone binds to
any DNA. So we call that the histone-DNA binding is specific, but non-

我要解释一下，
我压根不是做DNA damage/repair的，我有兴趣的一段疾病相关的序列repetitive

hypothesis是：这段疾病相关的repetitive序列或许更加vulnerable to 外界的DNA
damage， 或者DNA repair的修复能力跟其他普通序列不同，从而能为疾病机制提供新
的发现
我看了大部分DNA damage/repair领域的文章，我感觉大部分的工作都是global的比如
