I used this code
def x
puts "press return"
gets
end
class Foo; end
n = 100
x
f= Foo.new
n.times do |i|
f.instance_eval("@a_variable_#{i} = #{i}")
end
x
with n=100 ruby used 6.35M ( according to task manager), before and after
creating the variables
when n=100000000, it used 300M before I got bored of waiting
