NAME

PPI::Statement::Scheduled - A scheduled code block

INHERITANCE

   PPI::Statement::Scheduled
   isa PPI::Statement::Sub
       isa PPI::Statement
           isa PPI::Node
               isa PPI::Element

DESCRIPTION

A scheduled code block is one that is intended to be run at a specific time during the loading process.

There are five types of scheduled block:

   BEGIN {
         # Executes as soon as this block is fully defined
         ...
   }
 
   CHECK {
         # Executes after overall compile-phase in reverse order
         ...
   }
 
   UNITCHECK {
         # Executes after compile-phase of individual module in reverse order
         ...
   }
 
   INIT {
         # Executes just before run-time
         ...
   }
 
   END {
         # Executes as late as possible in reverse order
         ...
   }

Technically these scheduled blocks are actually subroutines, and in fact may have 'sub' in front of them.
