| This foilset mainly extends the previous Perl Overview with a discussion of some key Perl5 capabilities. However, some topics may be advanced Perl4 features |
| We give an initial summary of Perl5 changes and then discuss: |
| Some old and new functions in Perl |
| Regular expression enhancements |
| New syntax, especially -> and => |
| New subroutine calling and declaration syntax |
| Hard (address) and soft (symbol table) references |
| General data structures, including multidimensional arrays |
| Object-oriented features: packages, classes, and methods |
