I have used it habitually because it contriubutes more to readability to reuse the same name than force yourself to invent new names for something that is conceptually the same, just transformed to match some formalities, like coercing strings to integers or keywordizing them.
A second way this contributes to readability is reducing the mental load by making it obvious that the earlier value will not be needed in the rest of the function code. This idiom is useful enough to have gotten its own macro in 1.5: (as-> (+ 1 1) mega (+ 1 mega) (+ 1 mega) (+ 1 mega) (+ 1 mega)) It expands to the exact form you have posted. -marko On Tuesday, April 2, 2013 9:09:25 PM UTC+2, larry google groups wrote: > > > If Clojure is suppose to emphasize immutability, why can I do this: > > kiosks-clojure.core=> (let [ > #_=> mega (+ 1 1) > #_=> mega (+ 1 mega) > #_=> mega (+ 1 mega) > #_=> mega (+ 1 mega) > #_=> mega (+ 1 mega)] > #_=> mega) > 6 > > I might as well be writing PHP code. > > Does anyone actually write Clojure code like this, or is it considered bad > form? > > > -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
