+Also, the practice of "code golf" is slightly de-emphasized; Perl 6 is

 As a result, there are various places in the syntax where whitespace is
 optional in Perl 5, but is either mandatory or forbidden in Perl 6. Many of

 However, note that you can use L<unspace|http://design.perl6.org/S02.html#Unspaces>
 to add whitespace in Perl 6 code in places where it is otherwise not
 allowed:
