Another good idea (probably in addition to this, but even on its own) would be to add an is_open() function, that takes an integer and test whether or not that integer currently can be used to represent a valid, open file.

There is a problem with this. 

integer fn = open(this) 
close(fn) 
integer fn2 = open(that)

Both fn and fn2 will have the same value (3)
