libsyntax-keyword-dynamically-perl 0.13-1build3 (ppc64el binary) in ubuntu oracular

 Syntax::Keyword::Dynamically provides a syntax plugin that implements a
 single keyword, dynamically, which alters the behaviour of a scalar
 assignment operation. Syntactically and semantically it is similar to the
 built-in perl keyword local, but is implemented somewhat differently to give
 two key advantages over regular local:
 .
  - You can dynamically assign to lvalue functions and accessors.
  - You can dynamically assign to regular lexical variables.
