libsyntax-keyword-match-perl binary package in Ubuntu Oracular riscv64

 Syntax::Keyword::Match provides a syntax plugin that implements a
 control-flow block called match/case, which executes at most one of a choice
 of different blocks depending on the value of its controlling expression.
 .
 This is similar to C's switch/case syntax (copied into many other languages),
 or syntax provided by Switch::Plain.
 .
 This is an initial, experimental implementation. Furthermore, it is built as
 a non-trivial example use-case on top of XS::Parse::Keyword, which is also
 experimental. No API or compatibility guarantees are made at this time.
