Hi, There is also this book : Clean Code: A Handbook of Agile Software Craftsmanship Some of you probably already knew about it, still it is good to recall :) Abdelghani |   | |   | |   |   |   |   |   | | Clean Code: A Handbook of Agile Software CraftsmanshipBook by Martin Robert C | | | | Afficher sur www.amazon.fr | Aperçu par Yahoo | | | |   | Date: Thu, 02 Jul 2015 07:37:11 +0200 From: Joachim Tuchel <jtuchel@objektfabrik.de> To: stepharo <stepharo@free.fr> Cc: Any question about pharo is welcome <pharo-users@lists.pharo.org> Subject: Re: [Pharo-users] an elegant way to return a result Message-ID:     <mailman.312.1435823336.8793.pharo-users_lists.pharo.org@lists.pharo.org>     Content-Type: text/plain; charset=utf-8 Just found this on twitter: http://www.cs.wm.edu/~denys/pubs/ICSE%2715-BadSmells-CRC.pdf Am 01.07.2015 23:35 schrieb stepharo <stepharo@free.fr>:

Ah, Okay, you are mentioning the one and only one case in which this could make sense.... ;-)

Something like

stream next ifNil: [^stream next].

so ugly. Please we should not teach how to do exception with blocks :)

...

So there may be cases where the two sends do not return the same result. But that is, of course, not what the OP suggested. Nevertheless, I was too fast in criticizing ;-)

I would consider code like that "less easy" to maintain, however.

Nice thinking Kata ;-)

ah yeah :)

I assumed

first "something aMsg" ~= second "something aMsg?

In case is the same, the correct way is as you say:

^ something aMsg ifNil: [ anotherResult ]

(sorry, he :P)

Make sense if there's code in between. not sure what you're saying. I mean, sending the message twice makes sense if you already know the outcome? Hmmm...

...

something aMsg ifNil:[ ^ something aMsg ]. "yay for guards!" "much more code" ^ aNotherResult
