> While it is syntaxically possible to use range subexpression for accessing array properties
> {code:java}
> x = stringbuilder("qwerty"); x[0..2]{code}
> It is not allowed now to use range subexpression for setting array properties, for example the following code
> {code:java}
> x = stringbuilder("qwerty"); x[0..2] = "qq"; {code}
> throws a parsing exception {{org.apache.commons.jexl3.JexlException$Assignment: "qq"@1:40 assignment error near '... qwerty"); x[0..2] = "qq"; x ...'}}
> Nevertheless the following code parses and executes as expected
> {code:java}
> y = 0..2; x = stringbuilder("qwerty"); x[y] = "qq"; x{code}
> It would be more convenient to have inline range subexpressions allowed for accessing arrays for both getting and setting
