Re: [ease-dev] Script shell prints [null] on no result

[Christian Pontesegger <christian.pontesegger@xxxxxx>]

Javascript is even more annoying

a = 1
     1.0
var b = 1
    [null]

So the 'var' keyword changes behavior here. I see that in some cases it 
would make sense to return the 'null' representation of the target 
language like you described in your post. For that we could avoid 
transforming the PyNone object to 'null' when we convert it to the java 
world. Possibly this is an option. However when your script returns 
something (eg to another script, to a shared storage, etc) you do want 
to have script language independent artifacts. PyNone would be of no use 
to anything else than Jython. Even another python interpreter would be 
lost with that specific object.

Also 'null' could be used as an input value for a Java method - and 
might make sense in some cases. PyNone would be problematic here.

So I see use cases for both ways of implementation. Personally I am not 
sure which one is better. Having preferences for that is also not very 
promising as different installations of EASE might get incompatible to 
each other.

I do see your point here but cannot think of a clean implementation so 
far. We have to decide for one way or the other, both have benefits and 
drawbacks depending on your use case.
