Well, yes, that certainly addresses the issue, and I suspect that 
others have been thinking about it. I certainly have. But, remember 
when I said that this conversation will cascade? What about the other 
functions that take strings instead of well defined types? What about 
the other conversations that would be useful? I've got several dozen 
functions I'd like to see added, but I held back because I wanted to 
see 2.0 wrap in a timely manner.

I don't want to see us adding new functions at this point because I 
don't think we have the time to think carefully about them, and I don't 
think we'll have the chance to think carefully about which functions to 
add/change and which to exclude.
