C++ seems to have no problem with these smile
string could be at least inserted optional, so that we'd write the sentence 'mary goes, to school?' 2 ways:
/echo mary goes $+ $chr(44) $+ to $+ $chr(60) $+ $chr(60) $+ $chr(60) $+ $chr(60) $+ $chr(60) $+ school $+ $chr(999)

/echo "mary goes, to       school?" 

which is easier?
i don't really know what chr's are for blank spaces and quotation mark, so i wrote 60 and 999 randomly....
