Perl language structure. Perl data types – classifications identifying various types of data, that determine the possible values for each type; the operations that can be done on values of each type; the meaning of the data; and the way values of each type can be stored.

The Perl language includes a specialized syntax for writing regular expressions (RE, or regexes), and the interpreter contains an engine for matching strings to regular expressions. The regular-expression engine uses a backtracking algorithm, extending its capabilities from simple pattern matching to string capture and substitution.
Wall developed the Perl interpreter and language while working for System Development Corporation, which later became part of Burroughs and then Unisys. [5] He is the co-author of Programming Perl (often referred to as the Camel Book and published by O'Reilly), which is the definitive resource for Perl programmers; and edited the Perl Cookbook.
Larry Wall, creator of the Perl programming language (see Perl and Raku). Martin Odersky, creator of Scala, and previously a contributor to the design of Java. Martin Richards developed the BCPL programming language, forerunner of the B and C languages. Nathaniel Rochester, inventor of first assembler (IBM 701).
The Raku design process was first announced on 19 July 2000, on the fourth day of that year's Perl Conference, [10] by Larry Wall in his State of the Onion 2000 talk. [11] At that time, the primary goals were to remove "historical warts" from the language; "easy things should stay easy, hard things should get easier, and impossible things should get hard"; and a general cleanup of the internal ...

Perl later expanded on Spencer's original library to add many new features. [18] Part of the effort in the design of Raku (formerly named Perl 6) is to improve Perl's regex integration, and to increase their scope and capabilities to allow the definition of parsing expression grammars. [19]
