libsyntax-keyword-gather-perl 1.003001-1 (ppc64el binary) in ubuntu zesty

 Syntax::Keyword::Gather is a Perl syntax extension (see libsyntax-perl)
 that provides the "gather" control structure, which was inspired by Perl 6.
 It allows lists to be constructed procedurally, without the need for a
 temporary variable, by managing an implicit array within a closure.
