Question

Which programming language first came up with the finally block?

I ask purely out of curiosity.

It is a very useful piece of syntactic sugar, and whoever first created it surely has a very impressive grasp of solutions to programming problems.

(Note: it is deceptively difficult to find an answer to this question...)

Answer 1

According to wikipedia the first to introduce this was NIL.

The cleanup behavior now generally called "finally" was introduced in NIL (New Implementation of LISP) in the mid- to late-1970s as UNWIND-PROTECT.
