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;
PPI::Statement::Compound has a number of methods in addition to the
standard PPI::Statement, PPI::Node and PPI::Element methods.
The type method returns the syntactic type of the compound statement.
There are three 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 statement, but again does
not describes simple statements with a trailing while.
The 'for' type covers both of 'for' and 'foreach' statements.
All of the compounds are a variation on one of these three.
Returns the simple string 'if', 'for' or 'while', or undef if the type
cannot be determined.
