Re: Error: value of type 'proc (){.gcsafe, locks: 0.}' has to be discarded

[Arrrrrrrrr]

I have read this rust article on errors messages 
[https://blog.rust-lang.org/2016/08/10/Shape-of-errors-to-come.html](https://blog.rust-lang.org/2016/08/10/Shape-of-errors-to-come.html)
 and still can't see why having something like that in nim (implying there was 
enough colaboration) would be bad or undesired.
