The 'name' function is a clojure function that returns the string for a keyword, symbol, or string.
name - function
Usage: (name x)
Returns the name String of a string, symbol or keyword.
At first glace this might not seem that interesting; however, it's good to know 'name' if you've ever been surprised by (str :foo) => ":foo". If you have a ruby background (as I do), you probably expected the result to be "foo", spent a bit of time looking, and found that (name :foo) was actually what you were looking for.
That's helpful, but not particularly exciting. Perhaps a more interesting application of name is the ability to normalize all keys as strings and destructure. For example, say you're designing a library that monitors threads and you want to be able to pass in warning and error thresholds. Usage of your functions may look like the following examples
