I like abstraction. But I think names and order of computation should be changed to be more Smalltalk friendly. Because now it looks like Haskell with right to left order: squares := Set <~ 1000 take <~ #squared map <~ (1 to: 1000). fileOut writeStream <~ #isSeparator filter <~ fileIn readStream. Is there any reason to not change it? I would like to start expressions with source of data: squares := (1 to: 1000) ~> #squared map ~> 1000 take ~> Set. fileIn readStream ~> #isSeparator filter ~> fileOut writeStream. > Am .11.2017, 16:18 Uhr, schrieb Sven Van Caekenberghe <[email protected]>: > > >> >> On 14 Nov 2017, at 16:00, Steffen Märcker <[email protected]> wrote: >>> >>> Hi, >>> >>> <---Schnitt---> > >> >>> No. Transducers is my side project.
