a = 0
1.upto(3) do |a|
  # some code
end
# a is now 3

Iterators don't introduce a new scope for previously defined variables.  It's
in the documentation but anybody who's just learning "on the fly" will
certainly find this surprising. It's my least favorite feature about Ruby
because while everything else feels right, it feels dead wrong(coming from
Perl's lexical scoping rules).
