Query: On separable nets in constructive topological spaces   A class of nets in constructive (in A.A.Markov's sense) topological space for
which the convergence is equivalent to convergence of all subsequences, is
described. B.A.Kushner's theorem about coincidence of strong and weak
constructive variants of Riemann's integrability, is obtained as corollary.
