Re: OK idea to replace conj and cons with "prepend" and "append" macros that have consistent behavior and return same types as args?

To return to OP's question -- Good idea? Answer: At first, I saw the standard library as a mud puddle, an inkblot with just chaos, no airplane or number 42 in it. Then I got this book: Clojure Programming - Practical Lisp for the Java World - by Chas Emerick, Brian Carper, Christophe Gra

Ah, this came in with 1.5: https://dev.clojure.org/jira/browse/CLJ-910?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel On Fri, Jul 20, 2018 at 12:38 PM Gary Trakhman wrote: > > The memfn docstring says it can be type hinted to avoid reflection. Any > reason why it would still b

Re: How define alias for .indexOf? (def somealias .indexOf) does not work.

> The memfn docstring says it can be type hinted to avoid reflection. Any reason why it would still be slower then wrapping it in a type hinted function? Neat, I didn't know that! Since each memfn creates a new function, it's the same thing as writing it out manually, unlike say 'partial', which i

@Gary Johnson, your post is otherwise great, but I think a little confusing for this point: > , I would advise you to use the "into" function that I demonstrated at the beginning of this email if you wish to teach a unified API for appending and prepending to each of Clojure's four main data struct

Re: OK idea to replace conj and cons with "prepend" and "append" macros that have consistent behavior and return same types as args?

Hi Christian, You are looking for "into", which is already part of the Clojure standard library. Appending: (into '(1 2) '(3)) ;=> (1 2 3) (into [1 2] [3]) ;=> [1 2 3] (into {:a 1 :b 2} {:c 3}) ;=> {:a 1, :b 2, :c 3} (into #{:a :b} #{:c}) ;=> #{:c :b :a} Prepending:
