Hi, that's because you need to pass a block, since you want to postpone to execution. i.e. false and: [Transcript open]. (otherwise the binary operation Transcript open will take precedence over keyword false and:) You can always look at the implementation of those things â I always learn something from it. :) »and: alternativeBlock« Peter On Fri, Apr 3, 2015 at 12:10 PM, Jan B. <bliznjan@fit.cvut.cz> wrote:
Hello
I would like to ask how to do non-evaluating and. As far as I know, & should be evaluating and and: should be non-evaluating. However, I need to find a way how to use it properly.
In "conventional" languages I would expect to work it like in following example... false and: Transcript open Since false is... false... there is no reason to evaluate Transcript open. But when I run this one in playground, transcript opens.
Any help is appreciated.
