NAME

       PPI::Statement::Compound - Describes all compound statements

SYNOPSIS

	 # A compound if statement
	 if ( foo ) {
	     bar();
	 } else {
	     baz();
	 }

	 # A compound loop statement
	 foreach ( @list ) {
	     bar($_);
	 }

INHERITANCE

	 PPI::Statement::Compound
	 isa PPI::Statement
	     isa PPI::Node
		 isa PPI::Element

DESCRIPTION

       "PPI::Statement::Compound" objects are used to describe all current forms of compound statements, as described in perlsyn.

       This covers blocks using "if", "unless", "for", "foreach", "while", and "continue". Please note this does not cover "simple" statements
       with trailing conditions. Please note also that "do" is also not part of a compound statement.

	 # This is NOT a compound statement
	 my $foo = 1 if $condition;

	 # This is also not a compound statement
	 do { ... } until $condition;

METHODS

       "PPI::Statement::Compound" has a number of methods in addition to the standard PPI::Statement, PPI::Node and PPI::Element methods.

   type
       The "type" method returns the syntactic type of the compound statement.

       There are four basic compound statement types.

       The 'if' type includes all variations of the if and unless statements, including any 'elsif' or 'else' parts of the compound statement.

       The 'while' type describes the standard while and until statements, but again does not describes simple statements with a trailing while.

       The 'for' type covers the C-style for loops, regardless of whether they were declared using 'for' or 'foreach'.

       The 'foreach' type covers loops that iterate over collections, regardless of whether they were declared using 'for' or 'foreach'.

       All of the compounds are a variation on one of these four.

       Returns the simple string 'if', 'for', 'foreach' or 'while', or "undef" if the type cannot be determined.

NAME

       PPI::Statement::Variable - Variable declaration statements

SYNOPSIS

	 # All of the following are variable declarations
	 my $foo = 1;
	 my ($foo, $bar) = (1, 2);
	 our $foo = 1;
	 local $foo;
	 local $foo = 1;
	 LABEL: my $foo = 1;

INHERITANCE

	 PPI::Statement::Variable
	 isa PPI::Statement::Expression
	     isa PPI::Statement
		 isa PPI::Node
		     isa PPI::Element

DESCRIPTION

       The main intent of the "PPI::Statement::Variable" class is to describe simple statements that explicitly declare new local or global
       variables.

       Note that this does not make it exclusively the only place where variables are defined, and later on you should expect that the "variables"
       method will migrate deeper down the tree to either PPI::Statement or PPI::Node to recognise this fact, but for now it stays here.

METHODS

   type
       The "type" method checks and returns the declaration type of the statement, which will be one of 'my', 'local', 'our', or 'state'.

       Returns a string of the type, or "undef" if the type cannot be detected (which is probably a bug).

   variables
       As for several other PDOM Element types that can declare variables, the "variables" method returns a list of the canonical forms of the
       variables defined by the statement.

       Returns a list of the canonical string forms of variables, or the null list if it is unable to find any variables.

   symbols
       Returns a list of the variables defined by the statement, as PPI::Token::Symbols.

TO DO

       - Write unit tests for this
