I second Lars's view.  I see nothing wrong with having a regex data type 
where you can precompile expression into and then later use it. The use 
of "n" (inline) and "N" for precompiled is not different than the use of 
"n" and "N" in cases of tl's and other places where we do support both 
"variables" as well as inline material that is used on the fly.

And I'm fairly sure that the convention is not causing issues once in use.
