Hi Daniel. your gut instinct is correct. The first code sample should be <a , b> as you suggest. The second has no result (the 7 is an error).
The corrected transcript should appear as; -----8<-----8<-----8<-----8<-----8<-----8<----- The verb ([) (left), also of infinite rank, provides pseudo-punctuation in the form of a statement separator a=.2 [ b=.3 a,b 2 3 which works because the above line is essentially a=.2[3 with the assignment to b taking place ‘in passing’. ----->8----->8----->8----->8----->8----->8----- Thanks Daniel, Regards Rob > On 5 Jun 2018, at 2:46 pm, Daniel Lyons <[email protected]> wrote: > > I'm staring at this code sample, which is the same on the wiki and in > the PDF, and not sure what I'm missing: > > -----8<-----8<-----8<-----8<-----8<-----8<----- > > The verb ([) (left), also of infinite rank, provides pseudo-punctuation in > the form of a statement separator > > a=.2 [ b=.3 > a,c > 2 3 > > which works because the above line is essentially > > a=.2[3 > 7 > > with the assignment to b taking place ‘in passing’. > > ----->8----->8----->8----->8----->8----->8----- > > I feel like this should be a,b in the first code sample, but I'm > perplexed by what might have been intended by the second code sample > there.
