Will you need a new keyword to enable your option for new keywords?

It works better if it is part of the language from the start.

Having said that, we can probably implement it using only existing keywords. Maybe: import java.lang.extensions.assert.

(I assume Java has some reserved part of the package namespace they can use for this purpose. Even if they don't, it shouldn't be difficult to find a package name that hasn't been used by anyone yet)
