Hi Ralph,

I think I maybe did something similar for groovysh, see here:
https://github.com/apache/groovy/blob/master/subprojects/groovy-groovysh/src/main/groovy/org/codehaus/groovy/tools/shell/Groovysh.groovy
In method evaluateWithStoredBoundVars()

I think this was based on some blog article by Guillaume about variable
bindings.

Hope that helps.
