Result of I need your experience - classification and comparison of languages

[Gabriel Moreau]

I don't understand why Effeil is more safe than Sather because Effeil 
use covariance (not safe) and Sather contravariance (safe).

One really nice features in Sather is Iterator you don't find in any 
other languages. You can find iterator in Ruby but they are not as nice 
as in Sather. Iterator are a very safe features because loop are clean 
and many bug comes from loop.
