Builtin Lambda

The Lambda builtin function is used to create custom functions, optionally with a specified name, a certain number of arguments, and a return value.

Use

    (\ {optional_name arguments} {return value}) (optionally pass arguments)

Examples

The following is a function that adds twelve to a number:

    dagger> (\ {x} {+ 12 x}) 1
    13

We passed in 1 as an argument, and it returned 13. (12 + 1)

We can bind a symbol to a function to reuse it many times using "set":

    dagger> set {addtwelve} (\ {x} {+ 12 x}) 
    ()
    dagger> addtwelve 1
    13
    dagger> addtwelve 4
    16
