[CLJ-1103] Make conj assoc dissoc and transient versions handle args similarly Created: 04/Nov/12 Updated: 23/Nov/13
|Affects Version/s:||Release 1.4, Release 1.5|
|Patch:||Code and Test|
A discussion came up in the Clojure Google group about conj giving an error when taking only a coll as an argument, as opposed to disj which works for this case:
I looked through the rest of the code for similar cases, and found that conj! assoc assoc! and disj! also had the same property, and there were some other differences between them in how different numbers of arguments were handled, such as:
conj handles an arbitrary number of arguments, but conj! does not.

clj-1103-make-conj-assoc-dissoc-handle-args-similarly-v1.txt dated Nov 4 2012 makes conj conj! assoc assoc! dissoc dissoc! handle args similarly to each other.

I too ran into this and started an additional discussion here: https://groups.google.com/d/topic/clojure-dev/wL5hllfhw4M/discussion
In particular, I don't buy the argument that (into coll xs) is sufficient, since into implies conj and there isn't an terse and idiomatic way to write (into map (parition 2 keyvals))
So +1 from me

Patch clj-1103-2.diff is identical to the previous patch clj-1103-make-conj-assoc-dissoc-handle-args-similarly-v1.txt except it applies cleanly to latest master. The only changes were some changed context lines in a test file.

Patch clj-1103-3.diff is identical to the patch clj-1103-2.diff, except it applies cleanly to latest master. The only changes were some doc strings for assoc! and dissoc! in the context lines of the patch.
