Your example shows reading an entire file into memory (string a
= readText("foo")), then iterating over that. I know you can
iterate over a string; I'm interested in iterating over a
stream, which is perhaps read over a network or from another
I/O source, where you can't assume you have access to all of it
at once - just one Unicode character at a time.
Oh, sorry I missed that. Take a look at
