Implementing `let` without using a macro
- by Matt Fenwick
I'm learning Lisp, and I've just gotten to let, which I don't quite understand (the implementation of).
A common definition for it is given in terms of lambda as a macro. However, nowhere have I seen that let must be implemented as a macro or in terms of lambda.
Is it possible to define let without using a macro or lambda?
I know it can be implemented as a primitive, but I want to know whether it can be implemented in Lisp without creating a macro -- by creating a special form or a function.
