That is interesting.

Part of the problem for me is that I really can't see well. this-that
and this_that kind of look the same to me.

Also, I do a lot of scala recently. That language uses _ as a
wildcard, so using _ in variable names (even though that isn't very
idiomatic of the platform) would be incredibly confusing.

Anyway, I can probably live with the underscores even though I've been
typing camelCase for 10+ years. The API is the real worry. I don't
like how many of the methods/functions are named. I think, was it
really so hard to call to_s to_string? When I type in an IDE, I
literally type "t" and press ctrl-space and select the method I want.
I can ctrl-shift-space and it'll just guess and type the rest of it
for me.

Part of this is experience. If you've been using perl, php, etc., then
the underscores look okay. If you haven't, then they don't.
Consistency is the key. That's also my problem with them. In PHP, you
never know if it's "teardown" or "tear_down". There are so many
problems with the API in PHP that it just left a massive sour taste in
my mouth. Of course, the same problem happens with camel case, but the
ide support for java has been much better than php, so it was less of
a problem ;)
