I'm not sure what you mean with pro tool.

All those vague concepts kept me away from learning rails because it always felt it was hacked together.

There are also a lot of PHP frameworks that have this pro status because they are hard to learn. But using comments as programming features doesn't sound pro to me.

Some time ago I jumpt fresh into C# and .NET MVC. Now that is what I call a pro framework. It was very easy to learn but so powerfull.

Ofcourse I'm biased now because I fell a little in love with C#
