1.    1.  GetOptions('coordinates=f{2}' => \@coor, 'rgbcolor=i{3}' => \@color);
   
2. 
   
3. The destination for the option must be an array or array reference.
   
4. 
   
5. It is also possible to specify the minimal and maximal number of arguments an option takes. foo=s{2,4} indicates an option that takes at least two and at most 4 arguments. foo=s{,} indicates one or more values; foo:s{,} indicates zero or more option values.

s{2}能用，s{,}、s{2,}、s{2,4}之类的都不能用
