Proper noun
(en proper noun)- „In addition to CGI, Perl 5 is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications. It has been humorously nicknamed "the Swiss Army chainsaw of scripting languages" because of its flexibility and power, and possibly also because of its "ugliness". In 1998, it was also referred to as the "duct tape that holds the Internet together", in reference to both its ubiquitous use as a glue language and its perceived inelegance.“
- „Perl'' was originally named "Pearl". […] The name is occasionally expanded as ''Practical Extraction and Report Language'', but this is a backronym. Other expansions have been suggested as equally canonical, including Wall's own humorous ''Pathologically Eclectic Rubbish Lister . Indeed, Wall claims that the name was intended to inspire many different expansions.“
- „It is often said that "Only perl can parse Perl''", meaning that only the ''Perl'' interpreter (perl) can parse the ''Perl'' language (''Perl ), but even this is not, in general, true.“
