I would like to do something similar to:

`curl -s http://example.com/some/file.bin >/usr/local/bin/foo`

Since `Shell` is polymorphic, I can probably do this with Turtle as-is, but all the examples operate on lines of `Shell Text` and I haven't internalized enough Haskell to navigate it. Is there an idiomatic way to get `Shell Bytestring` or another solution?
