=head1 NAME

Perl::ToPerl6::Transformer::Buiiltins::AddWhitespace - Format my(), our(), print()


=head1 AFFILIATION

This Transformer is part of the core L<Perl::ToPerl6|Perl::ToPerl6> distribution.


=head1 DESCRIPTION

Perl6 requires whitespace after C<my>, C<our>, C<print> etc. in order to not confuse these builtins with methods:

  my() --> my ()
  our() --> our ()
  print() --> print ()

=head1 CONFIGURATION

This Transformer is not configurable except for the standard options.
