Henri Biestro commented on JEXL-190:
------------------------------------
I usually put 'default' functions in the context (i.e extend JexlContext and
implement functions as methods of that class) and only use 'named' namespaces.
But nothing in the code precludes using a 'null' namespace.
Your use-case fix is thus; when solving a function call (without a namespace),
if a variable in the context exists with that name, it will be evaluated and
used. The code expects this variable value to be a 'function' object (i.e.
something that can be called like a function; a method, a closure, etc) and
will fail at runtime if not.
This only restates the fact that a variable - local or global - can mask a
(default) method.
> local function within context is not resolved if function resolver class
> without namespace is specified
