What I've done is (dummy) iterate the sequence immediately in the enclosing function after piping through Seq.cache. I'm not sure if this is the most elegant way. But, it works.
I suggest you to use File.ReadAllLines in conjunction with Array module.

I'm having a bit of a problem figuring out how to generate a sequence from a list of variables in a text file.
Right now, I have (simplified):
use txtrdr = new System.IO.StreamReader( listFilename ) txtrdr |> Seq.unfold (fun txtrdr -> let line = txtrdr.ReadLine() Some(line, txtrdr) )But, since the seq doesn't get iterated until the txtrdr is disposed, it doesn't work.
I also tried using a seq{} expression. But, it complained about the try/with (omitted) that I have for failed reads.
