Enable user mode REPL (: power) from script

I am trying to dynamically interpret a string as a command in Scala. To do this, based on what I understand, I need to call intp.interpret("string")(where intpdoes the current interpreter mean stringfor my command) while in power mode, right?

However, my problem is that I want to do this from within the script. So I'm looking for a way to switch to user power mode from within the script, and then call intp.interpret.

Is there a way to do this switch from inside the script file?
