I'm for not voting. As said previously this appears to be more of a religious-like issue more than anything else. For me, an amateur hobbyist programmer, I'm in favor of case insensitivity, however ignoring the underscores does seem to be more non-intuitive.
On a similar note, Nim has Uniform Function Call Syntax with the addition of being able to call procedures without parentheses. This allows one to get the length of a string four different ways. For myself this was a much harder adoption as a new user when compared to case insensitivity. My concern is that a vote on case insensitivity could very easily lead to a vote on this feature as well, and I've personally come to appreciate this feature a lot more than case insensitivity. If that were to happen, a vote on removing some of the other of Nim's stand-out features could be next... In addition, these are features that make Nim more enjoyable to program with, which I suspect was one of the goals originally, and they give more choice/flexibility to the programmer.
