RFC 200, by Nathan Wiger: Revamp tie to support extensibility

Proposed on 7 September 2000, frozen on 20 September 2000, depends on RFC 159: True Polymorphic Objects proposed on 25 August 2000, frozen on 16 September 2000, also by Nathan Wiger and already blogged about earlier. What is tie anyway? RFC 200 was about extending the tie functionality as offered by Perl. This functionality in Perl allows one to inject program logic into the system’s handling ofContinue reading “RFC 200, by Nathan Wiger: Revamp tie to support extensibility”

Proposed on 25 August 2000, frozen on 16 September 2000 On polymorphism RFC159 introduces the concept of true polymorphic object. Objects that can morph into numbers, strings, booleans and much more on-demand. As such, objects can be freely passed around and manipulated without having to care what they contain (or even that they’re objects). WhenContinue reading “RFC 159, by Nathan Wiger: True Polymorphic Objects”

RFC 168, by Johan Vromans: Built-in functions should be functions

Proposed on 27 August 2000, frozen on 20 September 2000, which was a generalization of RFC 26: Named operators versus functions proposed on 4 August 2000, frozen on 28 August 2000, also by Johan Vromans. Johan’s proposal was to completely obliterate the difference between built-in functions, such as abs, and functions defined by the user. In Perl, abs can beContinue reading “RFC 168, by Johan Vromans: Built-in functions should be functions”

Day 10 – A Teaser

Santa has a special treat: a teaser if you will. A part of a chapter from the upcoming book “Migrating Perl to Raku”, to be published January 2020. Optimization Considerations If you are an experienced Perl programmer, you have (perhaps inadvertently) learned a few tricks to make execution of your Perl program faster. Some ofContinue reading “Day 10 – A Teaser”
