I believe a tool to "fix" variable capitalization already exists, maybe
Manuel can confirm that?

I mean, there's also mass inconsistency in LLVM and Clang about

[... some quick-and-dirty regexps later...]

In include/llvm: 6275 methods starting [a-z], 1491 methods starting [A-Z]
In include/clang: 5176 methods starting [a-z], 2884 methods starting [A-Z]

So it looks like we're more consistent with the coding standard than with
the opposite convention in our public interfaces. In headers in clang's
lib/, we're somewhat the other way around: 438 starting [a-z], 669 starting
[A-Z], and specifically in clang's lib/CodeGen, we have 244 [a-z], 345
[A-Z].

These numbers aren't entirely accurate, since they don't cover the vast
numbers of Visit*, Traverse*, and Transform* functions we generate with
xmacros.

Yes, I agree. I vaguely recall being told that the sticking point on this
in the past was a worry about it degrading the usefulness of tools like
'svn annotate'. If we're no longer concerned about that, perhaps it's time
to fix this once and for all.
