This is a great description of RPYs.

In fact, I propose that we put a hack into ResourceScript which stats  
the .rpy file after it's been run, and if it is more than 512 bytes,  
print a UserWarning like:

	Woah there, code cowboy!  It's likely you've misunderstood what RPYs  
are for.  Have you read this?

	If you are quite sure that you are not committing an awful hack that  
will bring doom to you and shame to your family, set  
__no_seriously_this_rpy_needs_to_be_this_long__ = 5192

where 5192 is a new maximum size based on the current length of that  
file, calculated for the user's convenience to include some extra  
padding for the new attribute.
