Hi Matej,

These look great! One minor comment for now:

I notice that everywhere you have to keep repeating

     pragma.enable("easy-return")
     pragma.disable("explicit-result-guard")

Sorry for this annoyance. With the soon to be posted 0.8.37c and all future 
releases, all these should work fine with

     pragma.syntax("0.9")

which should be less annoying.
