...my view specs after upgrading to 1.0.8. Is anyone else seeing this? To isolate the message I did the following setup: - create new rails project (with edge) - installed rspec and rspec_on_rails - ran rake spec - ran script/generate rspec_scaffold products - tried to run a builtin view spec Zach

Big cleanup of LDT code. This code has very little type checking and is not frequently used, so I audited the code, added type checking and size optimizations to generate smaller assembly code. First, just introduce some small definitions that will be used later.

I don''t believe this is a *feature* of rspec in the first place, just an not-so-ordinary way to organize some specs. Any chance of having this work as I expect?

...I am going to work on filtering the documenation and to create links and modify cpp style method names to ruby-style names. For example where it would say "wxApp::SetTopWindow" I would change that into a link "App::set_top_window" I hope to have more progress later tonight. Zach

...d end IMO is adds a little more readability when looking at an individual "it" behavior on a controller spec.
