=head1 NAME

Perl::ToPerl6::Transformer::BasicTypes::Strings::AddWhitespace - Add whitespace between q/qq and ()


=head1 AFFILIATION

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


=head1 DESCRIPTION

Perl6 q() and qq() delimiters require whitespace if you're using round braces,
otherwise they get confused with a q() or qq() function:

  q(Hello world) --> q (Hello world)
  q[Hello world] --> q[Hello world]
  qq (Hello world) --> q (Hello world)
  qq[Hello world] --> qq[Hello world]

Transforms only interpolated strings outside of comments, heredocs and POD.

=head1 CONFIGURATION

This Transformer is not configurable except for the standard options.
