Compilation error: #![feature] may not be used on the stable release channel

I'm trying to compile hunter in evil mode - release 1.0.2 and I'm getting this error:

error[E0554]: #![feature] may not be used on the stable release channel

error: aborting due to 4 previous errors

For more information about this error, try `rustc --explain E0554`.

I understand why this error occurs and how I might be able to fix - by using the nightly version of rustc but I was wondering whether you have any plans in not using non-stable features of rustc such as this. I'm using Arch Linux and rust version 1.33.0.

The need for vec_remove_item and fnbox is easy to remove. trivial_bounds probably as well, don't know about try_trait, have to test that. It would definitely be nice if hunter worked on stable rust, for sure.

EDIT: Right, so try_trait is used heavily so that ? can be used on Options in functions that return Result and I don't really want to give up on that. Maybe there's a way to get rid of it anyway, everything else is easy to remove, trivial_bounds isn't even used at all.

Can't really do anything about this until try_trait is stabilized, so I'm closing this.
