Re: [julia-users] python-like generators?

[Ralph Smith]

According to the manual, Tasks are coroutines. The Wikipedia article 
<https://en.wikipedia.org/wiki/Coroutine> relates them to generators.  For 
any recovering C programmers in the audience, this related article 
<http://www.chiark.greenend.org.uk/~sgtatham/coroutines.html> might remind 
you why you prefer to be here in the land of honest macros.

[Mauro]

Isn't this the same as tasks in Julia?
http://docs.julialang.org/en/release-0.5/stdlib/parallel/

Although, note that their performance is not on par with start-next-done
iteration.

[Tom Breloff]

I've used them, and I think a Julia Task is a better comparison. So while
the syntax is different you can accomplish the same thing.

[julia-users] python-like generators?

[Neal Becker]

julia-0.5 supports generator expressions, ala python, which is very nice.

Any thoughts on supporting the more general python generator functions, as 
described e.g.: https://wiki.python.org/moin/Generators?  I haven't used 
them much myself (well, once), but they seem a really cool idea.
