USING: kernel arrays math sequences ;

: close-match ( seq1 seq2 -- seq3 )
    swap [ swap [ (match-min) ] keep swap 2array ] curry map ;

: complement ( seq -- seq' )
    [ [ second ] map 0 prefix ] [ [ first ] map ] bi zip ;


! I plan to use this for seperating text from tags, 
! manipulate the text, and rebuild the document.

Annotation: fix!
