Implementing macros by using the use/import mecahnism
Macros are a killer feature of Lisp many have longed for Perl ...
... in fact, it has been possible for a long time to expand and "inline" a function at compile time.
All you need to do is to pair the import mechanism with a source filter so you can insert code cleanly without stepping into the usual trap of source filters.
Coupling that with Keyword::Simple you even have a macro mechanism at hand that works without a "use" statement.
To demonstrate the benefits, we will present various elegant solutions for DSLs, object models, and runtime optimization.
