+title: Lambda Functions
+---
+Lambda functions are values that correspond to a computation not yet performed.
+These can take arguments. Defining a lambda function returns the value that
+corresponds to the function itself, the `eval` computation must be used to
+obtain the value that the function computes.
+
+### DEFINITION
+{{< fatecode >}}(lambda (([T0 = TYPE] {S0 = String}) ... ([TN = TYPE] {SN = String})) [COMPUTATION]){{< /fatecode >}}
+
+Returns a lambda function taking `S0` ... `SN` of types `T0` ... `TN` as
+arguments and evaluating to `[COMPUTATION]`.
+
+### EVALUATION
+{{< fatecode >}}(eval [REFERENCE] [C0 = COMPUTATION] ... [CN = COMPUTATION]){{< /fatecode >}}
+
+Returns the result of evaluating the lambda function at `[REFERENCE]` given the
+parameters `C0` ... `CN`.
+
+## Examples
+{{< fatecode >}}(lambda ( (int i) )
+   (+ (var i) 1)
+)
+{{< /fatecode >}}
+
+{{< fatecode >}}(lambda ( (int i) )
+   (* (eval int_to_int (var i)) 2)
+)
+{{< /fatecode >}}
