Or, you could use this to keep it consistent with various other
block-modifying keywords:

Allowing you to use an Enum's name without the prefix is one of the
things I actually miss about Visual Basic.  Sure, requiring the prefix
is nice for the sake of organisation, but it gets *really* aggravating
after a while.
