presumably if you are doing random access on the file, it is in a known nonarbitrary text encoding (like utf8). in which case you can read/access the file with the binary routines and just use the appropriate text conversions to get data out.

Hi Ben,
Bad things:
* There's no way to implement fgetpos/fsetpos type functionality, because coders don't expose their internal state. (In fact, there would need to be a way to explicitly copy the state, since it may well include IORefs, Ptrs, etc.) Is this a serious problem?
Yes! This is an enormously serious problem. At least for me.
It's not a problem for writing files, but I really really really need this functionality when reading files. Reason: I'm often tooling around in very large (1gb or greater) files which happen to be sorted on some sort of index and I need to do binary search in them. To load all the file into Haskell or to do linear search is impossible.
Other than that, I rather like the design.
