How could a FailFast-library work?

What is Fail Fast? 

Short intro: http://en.wikipedia.org/wiki/Fail-fast

Why a FailFast-library?

• It could leverage a lot of nice checks that you don't bother writing your self (think NUnit Assert-method).
• It could throw a FailFastException that is different from exception types that are normal catched e.g. argument and state exceptions.
• It could have sanity checks... e.g. was that a field null that you turned into a NullArgumentException?
• It could help standardize the fail-fast principle.
• It could extendable for you to add your own types, checks and fails.
• It could be performance tested.
• It could be well-tested.
• It will be open source.
• ...

How would I use it?
