Inconsistent behaviour of dotted names
--------------------------------------

                 Key: JEXL-64
                 URL: https://issues.apache.org/jira/browse/JEXL-64

          Issue Type: Bug
            Reporter: Sebb
             Fix For: 2.0


Jexl behaviour with dotted names is inconsistent

this.is.a.test=null - OK
this.is.not.a.test=null - gives an Exception:

Perhaps this is intentional behaviour, in which case it would be helpful to document which
keywords are forbidden in variable names.
