>From this SO posting (http://stackoverflow.com/a/2416407/318902 ) it sounds
like ruby "class" variables are like C++ static member variables -- i.e.,
only one execution of the initialization (and one actual instance) for all
instances of the class. The second question is when does this happen --
with C++, it's via the static initialization routine, before main() is
called. This posting ( https://www.ruby-forum.com/topic/809975 ) says that
class variables are initialized at "class definition time", which I would
take to be when the second "end" is encountered above.
Can you use strace() to verify?
