Thanks I will have a look.
Would be good to have tests and getXXX is not that idiomatic of Pharo.
I will have a look.

I know that the existing code is using this getX stuff.

Yes, we continued the code following what was already there. Now it's probably time to improve it.

OTOH there's no test on this PR and we are adding a new feature. That's not right :P

My rewrite would be:

• Remove the object mutation from the getX methods
• Add a field containing the list of supported "entity providers" (an entity provider is something that respondsTo #value: and expects the token list as argument)
• Make the initial value of this list something like: { [ :tokens | self maybeGetClass ]. [ :tokens | self maybeGetPackage ]. [ :tokens | self maybeGetTag ] } (if we put a bit more work we can migrate the whole computeEntity method to a series of calls like that)
• Then the implementation of computeEntity is just entity := providers detect: [ :provider | provider value: tokens ].

I checked and it looks ok for now.
So I will integrate it.
