Case Sensitive vs. Case Insensitive Languages

Just had a random thought while I was looking at some code today.  It’s yet another argument in the case sensitive vs. case insensitive language battle. 

Do you really want this to be able to compile?

 class C1 {
  int M1;
  int m1;
}

Yes it’s an abuse and should absolutely be caught in a code review.  But at the same time, experience has taught me that if an evil thing can be done with a language, someone will do it.

And yes, sadly I’ve seen code like this before.
