My crazy (probably very stupid) idea for an mvc language

I’m not certain why but for a while now I’ve really wanted to write a sort of python/ruby-esque DSL on top of ASP.NET MVC. I am probably going a little crazy and this is a dumb idea but I thought I might as well write it down and get it out of my system.

It would look something like this:

controller User:
   //Actions are composed of method + name

   get Add:

      pass

   post Add(userInputModel):

       (homeInputModel -> User).save

       redirect controller:home, view:foo

//Automatic transformation of types (e.g. view model -> domain object)

transformation HomeInputModel -> User:

   HomeInputModel.Name <=> User.Name

   HomeInputModel.Email <=> User.Email

   HomeInputModel.Password <=> User.Password

//Validation of domain objects before they are persisted

validate User:

   //Basic boolean validation logic

   Name.Length > 0

   //More complex business logic requiring a code block

   Name n:

       if n.First() == ‘y’:

           ValidationException “We don’t like people who’s name starts with y”

model User:

   string Name

   email Email //Built in type’s for common forms of data, e.g. emails, passwords. Enables default validation

   password Password

   Many<Task> Tasks //Complex db relationships inbuilt

Underneath this would all compile to C# or IronPython using NHibernate & Asp.net mvc with various custom bits inbuilt. What do you think, am I going a little crazy?
