Dániel Dékány commented on FREEMARKER-215:
------------------------------------------
Oh, I see it finished with parse exception since then... Not sure how many
minutes it was. So, yeah, will have to figure out if we can prevent it to try
so many combinations before it's proven that the template is in valid. Can be
potentially difficult... Reminds me the problem with with regular expressions,
where practically infinite matching time can only be prevented if you severally
limit the language.
