But MacCarthy's original LISP 1 and LISP 1.5 do not have real lambdas. The lambda feature parametrizes a piece of code as a function literal, but doesn't capture anything. What they have is code parsed to a data structure, which is then susceptible to manipulation by the program before being executed. JS has some dumb textual eval, like the Bourne shell. They also have the concept of a symbol. And only one value that is false. |
