=head1 NAME
PPI::Token::Operator - Token class for operators
=head1 INHERITANCE
PPI::Token::Operator
isa PPI::Token
isa PPI::Element
=head1 SYNOPSIS
# This is the list of valid operators
++ -- ** ! ~ + -
=~ !~ * / % x
<< >> lt gt le ge cmp ~~
== != <=> . .. ... ,
& | ^ && || //
? : **= += -= .= *= /=
%= x= &= |= ^= <<= >>= &&=
||= //= < > <= >= <> => ->
and or xor not eq ne
=head1 DESCRIPTION
All operators in PPI are created as C<PPI::Token::Operator> objects,
including the ones that may superficially look like a L<PPI::Token::Word>
object.
=head1 METHODS
There are no additional methods beyond those provided by the parent
L<PPI::Token> and L<PPI::Element> classes.
