Subject: Re: [Ann] Verify, a very basic testing tool.

Not to be contentious, but you use both define_method and *_eval to
generate code.  Unless I don't know what that term means, I believe
you *do* use metaprogramming.

Though, I do have a question/concern/confusion/something.  I
completely and utterly fail to see the point of these new closure
obsessed frameworks or tools.  Nearly every bit of their functionality
could be wrapped up in a few simple helpers like this:

class Test::Unit::TestCase
  alias old_assert assert

  def assert(result = nil, &block)
    result = block.call if block_given?
    old_assert result
  end
end

Unless I'm totally missing something?  I realize it's a different
syntax or "DSL," and that's fine if that's your reasoning, but I don't
see how they're all that revolutionary.  I like closures as much as
the next guy, but I don't see how they revolutionize my testing life.

Aimed much less at you, and more at the 4-5 of these I've seen in the
past few days.
