I don't like to "eval" or anything like that; most of my metaprogramming in Ruby is based on the ability to place closures as methods.

I just found out an interesting "feature" of closures in Ruby. If you don't give an explicit parameter list in your block, Ruby doesn't complain if you pass arguments. See:

>> lambda{3}.call 2
=> 3
>> lambda{||3}.call 2
ArgumentError: wrong number of arguments (1 for 0)

f = Flex.new
f[:example] = 3

You probably already know this, but this is also what the OpenStruct class in the Ruby standard library does :-)
