custom pragmas are not supported for enum fields

[PMunch]

Well it's not obvious what you're trying to 
_[achieve](https://forum.nim-lang.org/postActivity.xml#achieve) I guess is a 
better phrasing. I can see that you're trying to add some information to an 
enum, which as you discovered isn't a thing you can do. The examples provided 
by me and @Calonger shows you how you can tie more information to enum values 
than what the regular int and string options they come with.
