You probably won't be. I have observed a similar phenomenon when trying to imagine truly new things.

If you can't figure it out in C++, but you could in (say) assembly (or Perl, or Python or whatever), then I would agree with that and would say I don't think that's an essential limitation of programming languages, and just that C++ is unfamiliar and byzantine.
But if you can't figure out the task in C++, but [believe] you could in [plain] English, I'd say you're just wrong: Whenever someone has told me "the ticket is perfectly clear" it most definitely was not. If your experiences are different, I'd like to hear about them.
This is not the case for programming languages, because programming languages, even non-imperative ones, only have one mode: how to do something. They are not a way of describing the world. If I can't figure out the C++ code necessary to accomplish the task I want, that doesn't mean I can't imagine what that task is. Determining the task and figuring out how to code them are very different.
