| Summary | APPLY: simplified, non-positional refinement value passing |
|---|---|
| Description |
This ticket is only a stub for now (needs a basic rationale explaining the brittleness of current APPLY with refinement arg passing). I thought we discussed and already designed this years ago but then couldn't find it written up as an issue anywhere, so I'll just quickly quote BrianH's re-discovery on SO chat (http://chat.stackoverflow.com/transcript/message/21704505#21704505):
"One way that you could do named-refinement APPLY is to pass in the refinement and options in the argument block, but choose whether to provide that refinement and its associated arguments to the function based on the value assigned to the corresponding word. So, apply :append [[] [5] /only] would pass on /only depending on whether the word only had a truthy value assigned to it." |
| Example code |
;; Another example: use [deep part length] [ last: false part: true length: 3 apply :take ["foobar" /last /part length] ; == "foo" ] |

Thanks for posting this placeholder; I'll flesh out the proposal when I'm able.
We never came up with this proposal before in any conversation I was aware of, but there were a couple years of conversations that I wasn't around for so I can't speak to what was said in them. However, the alternate proposal for choosing just based on the existence of the refinement in the argument list has been proposed over and over again, and again earlier in the conversation that you referenced. |
