Re: [julia-users] Proposed solution for writing Enums

They're still fairly informal:

   - https://github.com/JuliaLang/julia/issues/12139
   - https://github.com/JuliaLang/julia/issues/14052
   - https://github.com/JuliaLang/julia/issues/16878
   - https://github.com/JuliaLang/julia/issues/17115

Basically an extended issue proposing a design to solve a particular
problem.

What's an example of a good Julep? I did some searching and couldn't find 
much. Is there a document somewhere about
writing and submitting Julia Enhancement Proposals?

It's certainly possible. The best way to make it happen is to write a good
Julep for how case/switch should behave and once there's general agreement
on the plan, make a PR to implement it.

Julia indeed has built-in enums: Just below here in the docs:

@enum doesn't do what you want for enums?

It's a bit surprising that Julia doesn't have built in enums and a 
case/switch form. I'm glad that there's open
issue https://github.com/JuliaLang/julia/issues/5410 to address the lack of 
case/switch. Is there any hope that
we may see these (or at least the built in case/switch) in 1.0?

The formatting on that came out pretty garbled. Can you repost with line
breaks and such?

[julia-users] Proposed solution for writing Enums

2016-08-23 Thread Paul Sorensen 
The following is my idea of writing enums that are better than the macro 
because they give you a  typesafe way of passing them to a 
functionbaremodule EnumNameimmutable enumnamex::UInt8end
const Value_A = enumname(0)const Value_B = enumname(1)end# usage 
examplebaremodule Colorimmutable colorx::UInt8endconst 
Red = color(1)const Green = color(2)const Blue = color(3)const 
White = color(4)const Black = color(5)endfunction 
testColor(c::Color.color)println("A color was 
passed")endtestColor(Color.Red)
