Any sufficiently complicated concurrent program in another language contains an ad hoc informally-specified bug-ridden slow implementation of half of Erlang.

Example

nl(Blabber).
abcast

What's being called?

I think the lack of reusability comes in object-oriented languages, not functional languages. Because the problem with object-oriented languages is they’ve got all this implicit environment that they carry around with them. You wanted a banana but what you got was a gorilla holding the banana and the entire jungle.

If you have referentially transparent code, if you have pure functions-- all the data comes in its input arguments and everything goes out and leaves no state behind-- it's incredibly reusable. You can just reuse it here, there, and everywhere.

	Question 1
	The digits in the credit card pattern 4811 XXXX XXXX 2632 sum to 77, what are the
	middle 8?There are 112,400 card numbers (about 1.2%) in this range that 1) pass
	the luhn check and 2) sum to 77. The credit card isn't in great danger.

	Question 2Does the sum of the card digits make a good security question for
	phone support?The first hurdle is having a customer add the 16 digits without
	miss-adding or freaking out. Next, the numbers do cluster to the middle. A bad
