Sorry for jumping in late.
The Haskell expression you showed here is called a list comprehansion
which can be easily formulated as
map f xs
and this is in J simply:
f xs

In Haskell (and other languages I'm sure) one can express the idea of
"such that" to denote one expression depending on another. In Haskell
we can use the syntax:
[ f x | x <- xs ]
which means
"the list of all f x
such that x is drawn from xs."
So | is syntactically similar to the English "such that". (and very
much like | in mathematical sets)
I would like to know if J has a construct to express the above
Haskell code.
Thanks,
Jon.
