[lldb-dev] invalid use of 'this' outside of a non-static member function

[Greg Clayton]

All expressions are compiled in C++ mode and thus the restriction. 

There are a few solutions:
1 - make expressions match the current language of the current frame. So if your function was a C function, you will be restricted from using C++ in your expression
2 - rename your "this" and benefit from the C++ abilities of the expression parser 

I personally really like the ability to use "auto" and all of the C++11 constructs in any expression:

(lldb) expr for (auto x = 0; x < my_renamed_this; ++x) { ... }

So I see the problem with C expressions, but I would rather not limit you from being able to access your C++ code from a C function by limiting the language based on where you are stopped.
