I see your point as well. I think both versions have their place... it
just comes down to proper naming to reduce confusion. I'll think on method
names a little more.

I see your point. However, my gut is telling me that your solution still
conflates two separate issues. The first is, What's a good way to mutate an
array element by element with a function that takes a scalar input? The
second is, how do I "pipe" (is this still the right word?) the result of
o
I agree... using the pipe operator for this would be confusing at best, and
breaking at worst. However it would still be cool to be able to connect
multiple functions in one pass. What about:
julia> function foreach(A::AbstractArray, f::Function, fs::Function...)
for x in A
Pipe and map seem like related but orthogonal concepts; I don't know if
they ought to be given the same operator. But I may just be looking at
things wrongly.
I'd sooner see a tricked-out array comprehension syntax. Something like
![ add_one(x) for x in A ]
If the target array were ambiguous,
Stefan: Yes that's obviously valid. Simon's "foreach" is essentially what
I mean.
Although overriding the pipe operator would probably break things, I think
ideally there would be a built-in solution that looks similar to this:
julia> |>(A::AbstractArray, f::Function) = (for x in A; f(x); e
I wrote myself a foreach, which I'm using from time to time.
foreach(println, array)
It's not a big win, but in some cases it feels nicer than a for.

Any reason not to just use a for loop for this?
"map_without_result(add_one!, A)" is three characters longer than "for x in
A; add_one!(x); end" and the semicolons are unnecessary.

Ideally I don't have to assume anything about the return value (all I care
about is the side effect).

Not sue if this is exactly what you want, but you can achieve this with
`map!` by making `add_one!` return the modified MyType:
julia> type MyType; x::Int; end
julia> function add_one!(mt::MyType)
mt.x += 1
return mt
end
add_one! (generic function with 1 method)
