Draft JEP Announcement: "Computed Constants"

[Brian Goetz]

As Maurizio said, this JEP is a refinement of ideas that were initially 
explored in the "lazy statics" JEP.  In a way, this JEP reveals the 
"lazy statics" JEP as skipping a step, jumping to a language and VM when 
much of the benefit can be achieved by a libraries approach.  It is 
possible that at some point, after suitable progress and validation, we 
may decide to take the step of pushing it further into the language/VM, 
but we've made the deliberate choice to push such steps into the future.

In the meantime, there is no reason we cannot have multiple 
"inconsistent" draft or candidate JEPs, so there is no need to "merge" 
anything right now.
