I have no strong opinion on this, but I do wonder: is it the established style to not import the variants? And if so, is it established by virtue of being done that way everywhere or is it a conscious decision that's documented somewhere?

[alexcrichton]

I think it's not unheard of to import variants in some contexts (e.g. if they're used on basically every line in the file) but because they're not imported by default it's more idiomatic to access them through the enum itself (e.g. that affects how the variants themselves are named).
