 *A line whose first non-whitespace characters is a dot followed by a space (". ") does not open a new bracket: it is treated as simple continuation of the first less indented previous line*. In the first line this means that this line does not start with a bracket and does not end with a bracket, just as if you had directly written it in lisp without the leading ". ".

 ** Clarifications
 
 - Code-blocks end after 2 empty lines followed by a newline. Indented non-empty lines after 2 empty lines should be treated as error. A line is empty if it only contains whitespace.
 
-- square brackets and curly braces should be treated the same way as parentheses: They stop the indentation processing until they are closed.
+- Inside parentheses wisp parsing is disabled. Consequently linebreaks inside parentheses are not considered linebreaks for wisp-parsing. For the parser everything which happens inside parentheses is considered as a black box.
 
-- a colon (:) at the beginning of a line adds an extra open parentheses that gets closed at end-of-line (rule 4.2.7) *and* defines an indentation level.
