Do you mean something like this?

/// --- code ---
module test165;

import std.stdio;
import std.traits : isFunction;

void main()
{
	immutable b = [ __traits(allMembers, mixin(__MODULE__)) ];
		
	static foreach(i, _; b)
		static if(isFunction!(__traits(getMember, mixin(__MODULE__), 
b[i])))
			writeln(b[i]);
}

auto fun1(){}
struct S;
int i;
double[] arr;
auto fun3(int val){}
auto fun2(T)(T notAfun) {}
/// --- code ---

I saw a similar problem here:
