Lambdas

A lambda is an anonymous function defined inline. It produces a function pointer.

Syntax

lambda func <ret> _[<params>]
    <body>
end

Example

type F_T func int _[int, int]

func F_T make_adder[]
    lambda func int _[int, int]
        + return
    end
    return
end

The lambda produces a function pointer of type func int _[int, int].

No captures

A lambda cannot capture variables from the enclosing function:

func F_T make_adder[int n]
    lambda func int _[int]
        n + return    // error: `n` is not captured
    end
    return
end
