No, I'm saying that if function names are case-sensitive that you're an idiot if you use that feature to distinguish between two functions otherwise named identically with different (important) side effects. The fact that the parameter set is different implies auto completion by an IDE was probably partially to blame here (if you did it by memory you'd have gotten a wrong parameter count warning).

Some language features you best not exploit if you want to write reliable and bug-free (to whatever extent possible) code.

This is not a typo so much as it is a very poor choice of naming convention.
