How do I convert string that looks like this:
['Point Target', 'Channeled']
To an actual List of elements (in this example, Point Target and Channeled)?
You could use eval("['Point Target', 'Channeled']").
But be careful if you get the list from an untrusted source as eval will evaluate everything that it gets. So don't use it e.g on unfiltered input from a webinterface.

Given the following list:
a = [0,1,2,3,4,5]
In python I can do this:
a[2:4] which will get me [2,3]
Given that same list in groovy, is there a similar slicing mechanism I can use?
The answer is:
a[2..3]
another example would be if you wanted [1,2,3,4]:
a[1..4]
