Some of them could potentially be a little confusing as well, such as "delta" in game development, "echo" in some networking contexts, or "uniform" in OpenGL shaders. I don't tend to use single-letter variable names outside of the standard `for(;;)` syntax, but if I did, I don't think I'd replace them in this way.
