The problem is that a String allocates a buffer and so has to fill it eagerly.
You could implement http://java.sun.com/j2se/1.5.0/docs/api/java/lang/CharSequence.html. I don't know wether Seqs implements that. Else, you could use deftype to do it yourself, but it will be hard. If you just want to a something with the string, as printing it, then the best it too write it as a dorun of a smaller function. dorun do not retain the full structure in memory. Ex : to print something ---pseudocode, I am to lazy to test (dorun function-that-print-a-char lazy-seq-of-char) That would be the most idiomatic and simple, if you don't need to interface your String with Java.
