BTW, I don't know if you're using streams in a parser, but if you're using
them only as enumerations, you should consider using the Enum module instead
( Enum is part of the ExtLib : )

One example of conversion of a string enum to a char enum :

open ExtString
let to_chars e =
    Enum.concat ( String.enum e)

I don't know about the Stream implementation, but Enum are purely
functional. That means there is no temporary "char list" or "char array"
created anywhere, only a int ref in a closure actually.
