Perl Object Orientation

• Perl Reformed OO Syntax
• Perl5 vs Perl6 OO Syntax
• synopsis perll 6 OO
• Perl6::Bundle article on CPAN
• intro to OO, presentation

Requirements

• notation should be close to standard OO
• should not reduce execution speed much
• should allow flexible design
• should be usable piece by piece (e.g. only attribute accessors)

Candidates

• Use the existent mechanisms of Perl 5.8
• reformed perl
• Perl6::Classes
• Moose based onClass::MOP

Deficits of Perl5 OO

problem	Perl6	Moose	Reformed
Attribute Accessors
missing compact 'inherits from'	"isa"	"<"
usage of "->" instead of "."	solved	no

• own document: Perl Oo Perilipsis?

Attribute Accessors

• conveniently via
  • val = obj->attribute
  • obj->attribute = val
  • has overloadable global get/set methods, set('attribute', 'val')
  • has overloadable specific get/set methods, set_attribute('val')
