Sur une erreur de syntaxe [is xxx] où il manque le deuxième élément à comparer on reçoit ce genre de trace:

C'est quelque chose qui devrait sortir dès la définition du template, et même si ce n'était pas le cas il faudrait pouvoir remonter une erreur plus précise du style SyntaxError: "[is xxx]" is invalid syntax.
