This is really cool and kinda insane—running modern #Perl on the #Java Virtual Machine (#JVM).
Why? Maybe you want the flexibility of Perl scripts in your JVM-based environment (including #Kotlin and #Scala) without shelling out. More reasons here: https://github.com/fglock/PerlOnJava/blob/master/docs/WHY_PERLONJAVA.md
Anything with #XS or #FFI C code has to be ported to Java, mind you. But @fglock has been doing just that, e.g., #DBI support via #JDBC and #JSON via fastjson2.
