Ветка from __future__ import braces

это я так понимаю из темы риторики ) Why do programming languages, especially C, use curly braces and not square ones? The definition of "C-Style language" can practically be simplified down to "uses curly braces ({})." Why do we use that particular character (and why not something more reasonable, like [], which doesn't require the shift key at least on US keyboards)? Is there any actual benefit to programmer productivity that comes from these braces, or should new language designers look for alternatives (i.e. the guys behind Python)?
