PPI does not detect the dotted bitwise operators

[book]

These operators exist since Perl 5.22.

It fails with both regular version:

$ perl -Ilib -MPPI -MPPI::Dumper -e '
    PPI::Dumper->new( PPI::Document->new( \q{$x|.$y} ) )->print
'
PPI::Document
  PPI::Statement
    PPI::Token::Symbol          '$x'
    PPI::Token::Operator        '|'
    PPI::Token::Operator        '.'
    PPI::Token::Symbol          '$y'

expected:

PPI::Document
  PPI::Statement
    PPI::Token::Symbol          '$x'
    PPI::Token::Operator        '|.'
    PPI::Token::Symbol          '$y'

and the assignment version:

$ perl -Ilib -MPPI -MPPI::Dumper -e '
    PPI::Dumper->new( PPI::Document->new( \q{$x|.=$y} ) )->print
'
PPI::Document
  PPI::Statement
    PPI::Token::Symbol          '$x'
    PPI::Token::Operator        '|'
    PPI::Token::Operator        '.='
    PPI::Token::Symbol          '$y'

expected:

PPI::Document
  PPI::Statement
    PPI::Token::Symbol          '$x'
    PPI::Token::Operator        '|.='
    PPI::Token::Symbol          '$y'
