I write both C++ and Python all the time and I type enough underscores and caps all day just fine, thank you. The colon doesn't register for me when I'm writing those either. When it did register for me was precisely when I started designing my own language, attempted to design declarations with this exact syntax, played around with it, and realized this is a burden I'd never noticed before, and that this was one thing that made languages more pleasant to write in. Think of it like font kerning. Some people notice it, some don't, but most people prefer good kerning even if they never think about it.
