I'm really into partial application when you wish to mock some data for testing, and the caller chain of that test is shallow. That is:
* function under test takes in a data as its last parameter
* partially applied version of this function is used in a test
* testing function constructs fake data
* testing function calls the partially applied version
It's also nice for code reuse in libraries, but I'm generally less inclined to use it unless I know that the thing I'm working on has dead-simple requirements and won't change much.
