Thanks for the reply.
I assume from mutate you mean not changing type of the sub-variable (e.g
"vstate" above) ? I plan to change the values inside that vector but the
vector itself, both in length and type, will remain constant.

I didn't know that you can write

B(x)=new(b(x))

and thus get a very private function `b`...

Probably a good idea. But it does lead to the question of what exactly
should be allowed in type blocks. Obviously method definitions are
necessary, but at least global variable declarations are also sometimes
used.

Were we going to deprecate that, or make it an error?
Any code in the type block that doesn't look like a field declaration is
evaluated in the scope of the type block and has the effect of preventing
default constructors from being provided. So X is a zero-field type with no
default constructors.

You should be able to test this out locally without modifying Cairo.jl.
Your example code is probably close. You'll need to make sure you qualify
everything that's not exported by Cairo.jl. For example, I think you'll
need to use `Cairo._jl_libcairo` instead of `_jl_libcairo`. If

In 0.5 you can write this as:

You should test it and decide what to put in it by modifying your own
forked copy of Cairo.jl. This is what's great about open-source; you get to
exactly see and control what impact the changes you want will have before
they get added to the official software.

I'd like to open a pull request, but I wouldn't know exactly what to put in
it... :) I was wondering whether I could test the syntax of such a new function
first, without actually adding it to the Cairo module. It. It might not be
possible, of course...
If it's also sparse within the band, then you should probably use normal sparse
CSC and call cholmod. If the matrix is dense within the band, then we don't
have types for banded matrices yet but the lapack band cholesky should be
accessible.
Interesting read, thanks!
I guess I'll hold off implementing this until 0.5 lands, then.

In Julia, variables have types, and the compiler uses this information
to generate optimized code. The Python pattern of adding a variable or

A straightforward translation of the Python pattern would be to use a

My first idea use demo function println(x::UTF8String) at julia side:

The algorithm was fine, the issue was that sampling from a range of
integers was heavily optimized for the case of sampling repeatedly from the
same interval, rather than from different intervals. Since the Fisher-Yates
shuffle changes the interval for every sample, it was effectively a worst
case
Wrapping the array of bytes in a UTF8String object should do it. It's not
quite clear what you mean by "transfer".

Ok so basically what I want to do is impossible.
I could remove the encapsulation inside the main() function I guess, but
it's not ideal either.

Just to be clear, `include` and `eval` all works in global scope and
you can't add a local variable at runtime.

It would be easy to do this using the MPI.jl package. That's what I would
