What about a library function that does the same thing as system("ls") or 
system("ls -C"). I can think of several places where it would be useful. 
It could accept the directory as an argument, also the stream to output 
too (e.g. stdout or stderr) and perhaps a flag to do a column-wise listing 
(a la "ls -C"). I think this would be the hardest part to do; not sure how 
ls does it - unless there is something easy we could do with format 
conversion strings?
