A different spin on the same topic - I've been wondering what the 
anticipated changes to both the standard library and application 
code are going to be as a result of dip25 and dip1000. Is the 
expectation that use of the new annotations will be limited to 
select portions of code bases, or that they will become the 
predominant way to write D code?

Another spin - If a company has a team people building a 
code-base and decides to establish best practices, how might the 
facilities introduced by dip25 and dip1000 fit into those best 
practices?

Clearly, there will be a menu of options available to teams, 
applications, etc. But, I would expect there to be a small number 
of preferred, commonly adopted approaches. And, it would be 
preferable, though not necessary, that best practices and idioms 
used in the standard library were a good starting point for new 
adoptees and development efforts. Hence my question about both 
Phobos and application code.

Perhaps it's too early to answer these questions, but if there 
are expected outcomes it would be useful to understand them.
