What type of semantics is used in Perl?

124 views Asked by At

I am doing a project about Perl and I would like to know which type of semantics does it use (Denotational, Operational, or Axiomatic) but I can not find it anywhere. Any idea which kind does Perl use? Thanks in advance! :)

Formal semantics are a computer science thing, and are largely irrelevant in the context of real-world language implementations. For Perl 5, the behaviour of the perl program defines the Perl language. There is no specification or formal description of the semantics. If you really have to press Perl into your categories, then it might be possible to say that Perl is defined via operational semantics encoded in the perl interpreter.
