I'm new to Ruby and Rails, too. Chris' example is very cool - I hadn't
seen
"Module.const_get" before. A less sophisticated (and much more
dangerous)
way to do the same thing would be to use eval:
x = "Foo"
obj = eval("#{x}.new")
obj.class => Foo
Actually, good Rubyists can manage to construct whole classes (and
modules and definitions)
on the fly, not just objects. Cool stuff.
