Maybe like so:

export f
f(x) = g(x) * g(x)
function g end
end

Hi all,
This works:
f(x) = g(x) * g(x)
g(x) = x + 1
f(2)# 9
That is, f(x) isn't fully defined until g is defined.
But if f(x) is in a module it doesn't work:
module myfunc
export f
f(x) = g(x) * g(x)
end
using myfunc
g(x) = x + 1
f(2) # ERROR: UndefVarError: g not defined
That is,
Hi,
I'm creating a Julia type that conatins a Mmapped Vector. The intention is
that the binary file behind the Mmap vector is created when the type is
initialised and the file is deleted when the gc knows it's out out of
scope. I'm using a finalizer function to achieve the deletion.
My code is
Very interesting, thank you for writing and working on this!

When I open a new Julia 0.4.5 Notebook I get the error message: "The kernel

To attempt to debug this I went to the terminal and in Julia ran "using

When I open my code with a function call back my julia window turns to
close. but while compiling other code its going turn off.Can any body help
me to fix this problem ?

Thanks for the pointers! Having also struggled with private packages on 0.5 for
a while now, I tried below steps (a few times). No such luck.

I tried it on 0.4 and there the speed of zip seems fine.

Thanks Yichao, Mauro, and especially Tim for the explanations -- I'm glad I
ended up asking this question. I think I will end up just using a branch as
suggested.

Hi all,
I've posted a new blog post providing background for some current discussion
about how to extend julia's AbstractArray API. I should note that the blog
post does not present solutions, only problems, but for those of you
interested in how things work internally---or in being involved in

(Nice on the type assert, but worth pointing out that the 2-argument outer
constructor is not type-inferrable.)

Try zip. If you see a performance hit there too, it would be worth reporting
(as long as you're testing julia-0.5).

Yichao is right, because doing so won't help performance in any way (indeed,
it will hurt it massively compared to an `if a.b...` runtime branch in your
code). You get the performance benefit from multiple dispatch only when the
compiler knows the "value" ahead of time (e.g., when it's compiling
For the sake of example, suppose that the function has no vectorizing
version. But I found that
([x^2 for x in [1,2,9]]...)
is probably the most compact for my purposes --- thanks!
Cf https://github.com/JuliaLang/julia/pull/15516 , which would be
really, really neat.

Thanks for the quick reply! Yes, that would be wonderful.
I want to interface to a library that has its own garbage collection; that
library walks the stack to find potential objects that must be kept alive.
Therefore, all calls to that library must be done in the form
library_global_StackBott
Is it possible to chain iterators in julia efficiently? By chaining I mean
the following. I have a tuple of iterators and I would like to have a
function "chain" such that

is equivalent to
for i in chain(iters)

I found such a function in the
Hi,
Is there a preferred syntax for mapping a vector to a tuple? Eg an
alternative for (contrived example)
v = [1,2,9]
ntuple(i -> v[i]^2, length(v))
tuple([e^2 for e in v]...)
