From perldoc CGI:
A Lurking Trap! Some of the form-element generating methods
return multiple tags. In a scalar context, the tags will be
concatenated together with spaces, or whatever is the current value
of the $" global. In a list context, the methods will return a list
of elements, allowing you to modify them if you wish. Usually you
will not notice this behavior, but beware of this:
printf("%s\n",end_form())
end_form() produces several tags, and only the first of them
will be printed because the format only expects one value.
