Yes, I am aware of that. They are just small part of the whole proposal, but
currently implemented in such a way that it is not possible to use it in
e.g. static asserts and aliases like it was proposed.

I still think that proposal is good (no one pointed out problems with it).
It could be implemented as kind of compile time expression once, and then
used in other places. It allows also more expressiveness and predictable
syntax e.g. 
void call(T : class)(T instance) {} 
I hope that above mentioned issues with current design of IsExpression will
be eventually fixed somehow, sometime...

The strange think here is how minor issues (as most of community doesn't
have problem with it) suddenly emerges from deeps and good ideas (which
solve real problems) are sunken in the water... Well, I can give more
examples if you want :-)
