#### Multiple arguments
Also known as “[curried] functions”.
Nix functions take exactly one argument.
Multiple arguments can be handled by nesting functions.
Such a nested function can be used like a function that takes multiple arguments, but offers additional flexibility.

<LAMBDA>
It takes one argument and returns a function `y: x + y` with `x` set to the value of the argument.
This function takes one argument and returns another function `y: x + y` with `x` set to the value of the argument.
Example:

<LAMBDA>
Applying that function `f 1` to another argument yields the inner body `x + y` (with `x` set to `1` and `y` set to the other argument), which can now be fully evaluated.
Applying the function which results from `f 1` to another argument yields the inner body `x + y` (with `x` set to `1` and `y` set to the other argument), which can now be fully evaluated.
