Actually it was the transition from 1.8 to 1.9 where many gems were
incompatible because of block scoping changes. Proc was part of that
and where my gems had most problems ;). This was around 2008 and it
took a few years befor 1.9 became the standard and most had moved
across. But I still have some code that runs on 1.8 only. That is why
Guix has

Even though it has hardly any supporting modules in Guix.  Is that not
great? I think it is. Try and run Ruby 1.8.7 on most other
distributions today.

For Python2 we also have some C modules that are just not worthwhile
porting to Python3. Mostly because we are the only ones using them! It
it would take person months migrating them. We'll just live with those
and run them as external Python2 processes from Python3. That is
pretty OK even if it does not win points for beauty.
