I expected "read" to work directly on a Data.Text because Data.Text has an instance of the Read class, but it seems to fail:
An instance of Read means that read can *produce* a Text, not that it can consume one. read always reads from a String, as you can see from its type: Prelude Data.Text> :t read read :: Read a => String -> a (Note that it is the result type a in the context for Read.) See the Data.Text.Read module (part of the text package you already have installed) for how to do similar things with a Text as a source. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
