Daniel, good example.

In this commit you can see Rick "technoweenie" Olson (from rails core fame) updating his very own restful_authentication plugin with a similar approach. Although he directly stops using constants in favor of class variables with accessors.

The way Rails is moving to methods to access constants is truly a good interface.

Also if you were in rails land, then you can use silence_warnings {} block and perhaps use a method like that that takes a block and resets the constant at the end of the block.

def redefine_const(name,value)
old_value = Object.const_get(name)
silence_warnings { Object.const_set(name,value) }
yield
ensure
Object.const_set(old_value,value)
end
