Thank for the information. I think this thread have some good
point but :
1/ Nobody is even considering pure/nothrow/@safe .
2/ Many problems are not solved with lazy.
lazy in itself isn't bad, but it don't play well with other
features of the language.
A language that have many feature that don't integrate nicely
with one another already exists. It is called C++, it is a
reason that lead to D. We can do the same mistake again and
again, but it seems that E already exists.
I rather agree. However, if the language doesn't provide some
feature it doesn't mean there is no way to accomplish the task. I
would be interested to know how to do it.
