## examples

## fetch some words
#chop(@l = (<>));

## regexps for if one letter was omitted
#print(map($_."\n", omit_list(+1, @l)));

## regexps for if one extra letter was added
#print(map($_."\n", omit_list(-1, @l)));

## regexps for if one letter was screwed up
#print(map($_."\n", miss_list(-1, @l)));

## regexps for if two letters were transposed
#print(map($_."\n", transpose_list(@l)));

## possible matches if one letter were omitted
#print(map($_."\n", omit_list(-1, @l)));

## possible matches if two letters were transposed
#print(map($_."\n", transpose_list(@l)));


## check for possible collisions if one letter were omitted
#print(map($_."\n", nonuniq(omit_list(-1, @l))), "\n");

## check for possible collisions if two letters were transposed
#print(map($_."\n", nonuniq(transpose_list(@l))), "\n");
