Ambiguity

There are at least two other possible meaning of "Fréchet space". One is as a synonym for T1 space, and the other is the specific space of real sequences with the Fréchet metric $d((x_i),(y_i)) = \sum_i 2^{-i} |x_i-y_i|/(1+|x_i-y_i|)$: both these latter are mentioned in Steen and Seebach's, Counterexamples in Topology (2 ed.). One also has the concept of a Fréchet V-space and of a Fréchet–Urysohn space. Would it be appropriate to create a page Fréchet space (disambiguation)?
