I've discussed this with @timfel and it seems to be the semantically correct behavior. Python and Java strings are immutable while Ruby strings are mutable, so they cannot be converted automatically. However, you can do the following for the time being:
(Polyglot eval: 'ruby' string: '"foo"') primitiveUnbox
Please let me know if you have any suggestions for making this API a bit more sane for users. In the past, I have used asSmalltalk
(instead of primitiveUnbox
which is internal Truffle API) to let developers explicitly requests a Smalltalk object. Of course, this call fails if it's unable to convert to Smalltalk, but it would work for a Ruby string for example.
