(Did you mean 'uniform'? Or I don't understand this sentence.)

I agree that it is good to have one standard, but I think that this is 
the case here, more or less. And the standard is to give prefixes when 
we perform an action on a prefixed variable, and in attr_* arguments are 
not prefixed simply because this action (defining accessors) involves 
both the variable, and the newly created method, of which the latter is 
not prefixed. So they chose that you sort of specify the method name and 
not the attribute name.

I agree that writing attr_accessor :@a could be regarded as correct as 
well, because this would let anybody use the form they find more 
coherent with the rest of the methods, and it would seem more clear to a 
beginner (I remember my confusion when I first saw it).

TPR.
