scoping

>global by default: OMG! accidental globals!
solution: detect global accesses statically or dynamically; since you "shouldn't be using globals anyway", there is no problem with disallowing them period

>local by default: OMG! accidental rebinding!
oops, now instead of accidentally creating globals, you risk rebinding to existing locals instead of creating a new one. this is much harder to detect--enjoy your obscure bugs! combine this with forced hoisting of locals for extra fun I'M LOOKING AT YOU FIOC

>neither by default: god tier
no confusion; NO EXCEPTIONS

I like the latter approach because it allows me to define variables within if/else instead of defining an empty value before the conditional.

I like C so so much
