I was just looking at the code in the package. There was an 
earlier discussion on predicates. If you changed the 
Read/RefRead/etc structs to be something like below, then the 
user could add in a string of the assert. It's not really all 
that elegant, but I think you should be able to get it to work.

struct Read
{
	string visibility = "public";
	string constraint = void;
}

My ideal was to get something working where the lower and upper 
bounds were actual values, so you didn't have to pass the string, 
but I can see how that gets complicated. One problem I ran into 
is that you can't really make a struct templated in an optional 
way. For instance, the following won't compile (ignoring the 
complexity of making the asserts > or >=):

struct Read(T = void)
{
	string visibility = "public";
	static if (!is(T == void)) {
		T lower;
		T upper;
	}
}

void main()
{
	Read read;
}
