> Underscores require me to hit the Shift key. When writing prose, I only hit the shift once or twice per sentence. In Ruby, I have to hit the shift key every few letters. Awkward. Inefficient.

Oh my, oh my, how do people ever cope with that vile "having to hit shift" that have regular capitalisation of all nouns etc. Surely such a thing is impossible, as is hitting shift when you need an underscore.

I understand that some things could be more efficient, but "hitting shift" hardly qualifies in my opinion...
