А>_=linq <# from (p1,p2,p3) in ll select p1 #>;
А>Error 5 expected identifier but found '('


Варианты решения:

using Nemerle.Linq;
using System.Linq;

def l = [(1,1,"aaa"),(2,2,"aaa")];

// 1.
_ = linq <# from p in l select p[0] #>;

// 2.
_ = l.Select(p => p[0]);

// 3.
_ = l.Map(p => p[0]);

P.S.
Thanx to emperon
