note stefp I guess TIMTOWTDI. It is a question of emphasis, yours is on performance, mine is on readability and incremental building.<p> If I combine my idea of (ab)?using <code>.*</code> with the concept that one can hack perl6 to make one's own language, I would define a modifier that would turn consecutive non breaking line spaces into an implicit <code>.*?</code> subregex with <code>?</code> having its traditional meaning of non greediness. I am not sure it would be a so good idea though. Will be a good exercice anyway. <p> -- <a href="/index.pl?node=stefp&lastnode_id=1072"> stefp</a> -- check out <a href="http://texmacs.org">TeXmacs</a> <a href="http://alqua.com/tmresources/">wiki</a> 179555 179827
