I do. I have done so repeatedly for a decade now.

There are holes in the foundations of the languages. These hole 
prevent basic things from being possible at all. For instance, 
containers.

But the focus has consistently been on other feature which are 
nice to have. The problem, is that it doesn't matter how much 
nice to have things you have - and I'll grant you that D has more 
than most on this front - if there are holes in the foundations.

Lately, the focus has been on named argument, tuples, ImportC, 
and a few other things. All good things. There are a couple of 
these holes, but really, the limus test shoudl be: can i write a 
custom container class that behaves lice builtin slice do? If so, 
then we are probably in good shape. If not, then literally 
anything else we add to the language is a net negative as it 
increase complexity without tackling the bottleneck.
