Description

I can not understand the logic behind the current implementation of JexlScript.getVariables() method. From the documentation we know that the result should be the set of script variables. For the code

a[b][c]

it gives three variables a, b, c. So far so good. But for the code

a[b]['c']

it returns a and b c, where second variable has two fragments b and c. The documentation states that variables with multiple fragments are ant-ish variables, but I don't have any of ant-ish variables in the example, and 'c' is not a variable, but a constant. I expect to get a and b as a result.
