I want to discuss about this issue.
I agree that it is not CRuby specific feature
and RubyVM namespace is not good.

Background:

(0) Now, caller_locations returns array of
    ::RubyVM::Backtrace::Location objects.

(1) I don't care about class name of objects
    what caller_locations returns.

(2) ::Backtrace::Location seems good name.
    But I'm not sure that ::Backtrace is common class or module name.
    I'm afraid naming conflict.

Ideas:

(a) Don't care about conflict.
    Rename to ::Backtrace::Location.

(b) Don't touch any more.
    CRuby returns `::RubyVM::Backtrace::Location'.
    But make it not spec.
    Spec is "This object should respond to several
    methods which ::RubyVM::Backtrace::Location has".

(c) Other names.
    Such as `::BacktraceLocation'.
    Ah, this is good name because it is long
    and maybe no conflict with existing code  (I googled it), isn't it?

I think (c) seems good now.

Thanks,
Koichi
