How to do it with not just 1 slice but 2 slices, and at the same time avoid Merlyn's issue of . and .. not always coming at the start of the list

@l = readdir(PRINT) ;
%h{@l} = (1) x @l ;
delete @h{'.', '..'} ;
for( keys %h ) {
  # do work
}

This is probably not what was desired in the first place, since it adds more lines of code, but I thought this would be interesting.

Nuts and Bolts

@l = readdir gets the list of files

%h{@l} = (1) x @l converts the list into a hash, since all elements in a directory are unique

delete @h{'.', '..'} removes the . and .. entries from the hash at whatever position they're hiding in.

for( keys %h) { . and .. free looping
