Interesting proposal for Error handling and Null through unified option Type.

[planetis]

My concern is post-fix operators don't work well in Nim. Also IMO dotOperators 
are a giant hack using templates, I have seen exactly one good use of it when 
turning JSON keys to object fields. The rest, namely trying to create sugar for 
options don't work that well. You need to support `.()`, `.=`, even `.[]` and 
`.[]=` And please make the language simpler to understand, not riddled with ?, 
! and what this proposal describes.
