i think it'd go something like:

Class String
	alias :to_i_orig :to_i

	def to_i
		fail "#{self} is not a valid integer" unless self =~ /^\d*$/
		to_i_orig
	end
end

I don't like the default behavior of String#to_i and String#to_f to return
zero for any string that contains no recognizable numbers. I had thought to
write overriding methods like so:

Class String
	def to_i
		fail "#{self} is not a valid integer" unless self =~ /^\d*$/
		# call original to_i
	end
end

...but I don't how (if it is possible?) to call the original to_i. Am I
stuck
with using a new method name or a custom string class?
