It could be, but why would we want this? I can't think of any reason why 
we'd want someone able to specify * or .com or something similar as a 
valid email address (since that breaks with rfc822, which is what we 
reference for the datatype). Technically, we specify the datatype's 
identifier, but not the format of the datatype, so we don't actually 
have the freedom to re-define the type unless we define it from scratch.

Tim, do you have a specific use case that requires this? I'm trying 
hard, but I can't come up with a scenario where you need to pass two 
rfc822Names to the match function and can't instead provide a string as 
one parameter. Unless there's a real problem this solves, I wouldn't 
want us to confuse the rfc822Name datatype.
