    foo := someDefaultValue
    if someCondition {
        foo := someMoreSpecificValue
    }

Whoops, accidentally created a fresh, unused variable in the nested scope instead of changing the value of the original variable.

I do that frighteningly often.

Seems to be more an indication that Go's variable declaration syntax is just not good.

Yeah, var/type name makes much more sense than ambiguity.
