In fact, I did. It's not awful -- just looks so. If there were
defines for parts, it would be a lot easier to write. 

atext=[a-zA-Z0-9!#$%&'*+\-/=?\^_`{|}~]+ # taken from the RFC
quoted-string="([^"\\]|\\.)*" # that is, not-quote inside quotes, or an escape
domain-content=\[([^\[\]\\]|\\.)*\] # that is, anything in square brackets, brackets are escaped if inside the brackets

local-part = atext(\.atext)*|quoted-string
domain-part = atext(\.atext)*|domain-content

addr-spec = local-part @ domain-part
