Introduction

What is libparse-keyword-perl

libparse-keyword-perl is:

Parse::Keyword allows you to write keyword-based syntax extensions without requiring you to write any C code yourself. It is similar to Devel::Declare, except that it uses the Perl parser API introduced in Perl 5.14 in order to allow you to parse parts of things using perl’s own parser, rather than having to fake it with balanced brace matching or other fragile things.

NB! This module has fundamental errors in the way it handles closures, which are not fixable. Runtime keywords will never be able to work properly with the current design of this module. There are certain cases where this module is still safe to use (keywords that only have effect at compile time, or keywords that never call any of the parse_* functions), but that is limiting enough to make this module mostly worthless, and its author may not continue maintain it.
