Re: [Ocaml-lib-devel] Purpose of IO.nread

Fine, I can see why you might want a simpler interface in a 
general-purpose library.  I really did it that way because it was 
slightly more convenient with the code I'm using myself, but I guess 
that's not a very good design principle... ^^;

The only reason I didn't use Pervasives.input is that it doesn't promise 
to return the number of items you requested, even if that many are 
available - for all the other inputs, that does seem to be guaranteed. 
I'm not sure if it really matters or not.

Yes, the version you describe would work just as well for me.
