Is there something like Unqual that can remove the safety attributes
from
a type?
In such cases we have to ask what's your use case/purpose. Isn't
@trusted enough?

Well, for my signal implementation (Latest code: http://ideone.com/SM11K )
I have templates which accept functions, delegates and callable objects. I
used something like "static if(is(T == void delegate(int)))" to check if:
1. T is a delegate
2. it returns void
3. it takes one int parameter
In this case I'm only interested in these three points, I don't care if T
is @safe @trusted or @system, but the above check fails if T is @safe.
I found a solution though, I now do these checks with functions from
std.traits: ReturnType!(T) for the return type,
is(typeof(T.init(Init!(Types)))) for parameters and is(T == delegate).
Seems to work fine now.
