I opted for writing to stdout instead, because 1) it's easier, x) 
it's less code, and b) it's more flexible.

The memory limitations certainly do apply - readText would fail 
upon reading humongous files, and for 32-bit programs the 
resulting string wouldn't be able to hold enough data. Since the 
code uses ranges though, a simple replacement of readText with an 
mmapped equivalent should enable humongous file support with no 
other code change required.
