Issue with traits usability

[Márcio Martins]

Hi!

How do I get past this?


static struct X {
	int x;
	private enum T = 1;
	private alias M = string;
}

foreach (Member; __traits(allMembers, X)) {
	pragma(msg, __traits(getProtection, __traits(getMember, X, 
Member)));
}


Output:

public
private
c.d(1084): Error: argument string has no protection
c.d(1084):        while evaluating pragma(msg, 
__traits(getProtection, string))


What I want to achieve essentially is skip all X's aliases and 
templates, but get everything else, like enums and data members. 
How would I go about this in a robust way?
I actually want to skip aliases, and templates.
