Peter Alexander:
In general, it is not possible to have both full expressiveness and full performance.
The ShedSkin compiler has shown me that in some important cases this is not true. But even if in this case you are right, I am OK with that, because I write both performance-critical D code, and D code where high performance is not needed. A feature usable only in the second kind of functions is acceptable to me :-)
What I do know is that it is far too big a feature to be adding at this stage in D2.
Now maybe it's not the right moment to add important features to D, for various reasons. But maybe 2-3 years from now the situation will be different.
