# else-let

A Clojure library that adds an `else-let` macro for conditional binding in the face of `nil` values.

Inspired by Java's `Optional.orElseGet()` method, this macro evaluates the provided let statement and attempts to bind the variables to the first provided form,

if that form returns `nil`, `else-let` will bind the value of the second form.

Example:

```clojure

(else-let [x "first-value" "fallback"

           y nil "will bind this value to y"

           z nil nil]

           (vector x y (nil? z)))

;["first-value" "will bind this value to y" true]

``` 

## Usage

### 

```clojure

[else-let "0.1.0"]

```

### Maven

```xml

            else-let

            else-let

            0.1.0

        

```
