I don't know the real reason, but I imagine it would be that it would be 
very rarely used.  It would need to be an attribute that isn't a valid 
identifier, and you know the attribute at the time you write the code.

I can see scenarios for needing attributes that aren't identifiers, but 
in many of them you also need to access them through a variable rather 
than literally.
