Subject: Re: [Jprogramming] Flattening a list containing boxed elements
I'm still at the stage where I have to read the dictionary entry for most of
the verbs, so I'm not even in the slow lane yet. Looking at Stitch (dyadic
,.)[1] I was reminded of the explanation of u"_1, which suggested using Link
(dyadic ;)[2]
g =: }. @ (; @ (;"_1))
' ' g t
alpha bravo chuck
LF g t
alpha
bravo
chuck
if you like "pipelining" your verbs. (The outer set of parens aren't needed in
g , but that's a subtly different pipeline.)
