I believe that Ada allows case insensitive identifiers in order to prevent programmers from using the same names for different variables/procedures. Once I saw some C code like this: int x, X; X = 0; for(int i=0; i < N; i++) { /* long code to calculate the value of x */ ... X += x; } Personally, I appreciate that there are languages which prevent this, like Ada and Pascal.
