Hello !
Is there a way to catch an exception by type in Julia ? Coming from
python, I am very tempted to do this kind of things:
```
try
# Access a dict here
catch e
if isa(KeyError, e)
# Handle the KeyError, as I know what to do in that case
else
# Re-throw to upper level
macro need_m()
:(m * 20)
end
function algoX()
m = 10
@need_m
end
algoX()
# 200
I think you can create two similar macro to solve your problem.
But i think this is bad practice.
I think you should create some code without a scope, as I know, the macro
can do such

additional functionality with regards to exception handling.

Ok, thank you !
So the way to go is better ask for permission than for forgiveness !

Which is ok in this case, since working with a KeyError is a very un-Julian way
to check for key existence. You'll want to use

Well, as of julia-0.4.0-1454~ubuntu14.04.1 It still happens. By the way, I

Semantically, ones(n,1) creates a vector and not a matrix.
Why is ones(n,1) different from ones(n)?
The type system is very confusing and non-intuitive.

I'd rather say that in MATLAB ones(n,1) creates a vector.
This has been discussed many times on the list and in issues. In
particular, see the famous https://github.com/JuliaLang/julia/issues/4774.

Happy to see thus reaction from a core julia developer. Hope julia makes
parallel programming on CPUs and GPUs easier.
which I think is reasonable is a subjective argument.
It would be helpful if the type system is intuitive and non-confusing to
programmers.

What's intuitive is very dependent upon your background. If you're coming from
Matlab, for example, everything is a matrix and Matlab does this
extraordinarily-confusing thing:
ones(3,3,3) gives me a 3d array;
ones(3,3) gives me a 2d array;
but
ones(3)
ans =
1 1 1
1 1
I don't know what matlab does.
As a user, ones(n,1) and ones(n) both return me a vector, and it is
confusing to find that ones(n,1) != ones(n).

Your best bet, then, is to decide as quickly as possible whether you want to
use Julia. If you start reading here:

you'll maximize your chances of quickly discovering other things that will
likely annoy you :-). While
What about using multiple dispatch?
handle(::ExceptionType1, ::MyObject) = ...
handle(::ExceptionType2, ::MyObject) = ...
handle(::ExceptionType3, ::MyObject) = ...
handle(e::Exception, ::MyObject) = rethrow(e)
try
# Access a dict here
catch e
handle(e, dict)
end

characters going to the REPL.
Right now if I have

break
else

I would appreciate advise how to best implement the following:
I have an N^d array A, where the dimension d depends on the
application (d \in \{1, 2, 3\}). Somewhere else I have a list L which is a
d x M array or integers corresponding to points/elements in this array,
e.g. if
Thanks Simon and Tim.
You can do a lot better by dispatching on the dimension of A. Something like
this:
mygetindex{T}(A::AbstractArray{T,2}, L, Lcol) = A[L[1,Lcol], L[2,Lcol]]
mygetindex{T}(A::AbstractArray{T,3}, L, Lcol) = A[L[1,Lcol], L[2,Lcol],
L[3,Lcol]]
Put your timing loops in a function so you take

Dear Tim,
Many thanks - this was illuminating and helped me understand the
bottleneck. But it seems I did not give the correct amount of information
in my question. In fact, I also want to access A[ idx ] for general index
vectors idx that do not necessarily belong to the L array. For
