This is designed to work for Go, Perl, Python and Wren itself though see the remarks in the Go entry about using the first three languages and other more general points.
As far as Wren is concerned, in addition to Wren-cli programs, this should be able to run DOME, Wren-gmp, Wren-sql, Wren-i64, Wren-linear, Wren-regex and Wren-
However, no attempt has been made - at least for now - to run other embedded programs (which can be identified by the presence of the 'foreign' keyword) due to a number of technical difficulties in doing so.

We now embed this script in the following Go program and run it:
<syntaxhighlight lang="go">/* go run
package main
