       Perl::Critic::Policy::ControlStructures::ProhibitCascadingIfElse -
       Don't write long "if-elsif-elsif-elsif-elsif...else" chains.

AAFFFFIILLIIAATTIIOONN
       This Policy is part of the core Perl::Critic distribution.

DDEESSCCRRIIPPTTIIOONN
       Long "if-elsif" chains are hard to digest, especially if they are
       longer than a single page or screen.  If testing for equality, use a
       hash lookup instead.  If you're using perl 5.10 or later, use
       "given"/"when".

           if ($condition1) {         #ok
               $foo = 1;
           }
           elsif ($condition2) {      #ok
               $foo = 2;
           }
           elsif ($condition3) {      #ok
               $foo = 3;
           }
           elsif ($condition4) {      #too many!
               $foo = 4;
           }
           else {                     #ok
               $foo = $default;
           }

CCOONNFFIIGGUURRAATTIIOONN
       This policy can be configured with a maximum number of "elsif"
       alternatives to allow.  The default is 2.  This can be specified via a
       "max_elsif" item in the _._p_e_r_l_c_r_i_t_i_c_r_c file:

           [ControlStructures::ProhibitCascadingIfElse]
           max_elsif = 3
