Dmitri Blinov commented on JEXL-252:
------------------------------------
The {{object.`property`}} syntax alone, without interpolation, allow for more
special characters to be used. To me the idea of a property name being a
constant, seems not so important as the ability to use operators {{.}} and
{{[]}} differently semantically. For example I want to reserve operator {{[]}}
for accessing object by numbered indexes, like 1 or 1..3, lets call it array
semantics, and reserve operator {{.}} for accessing object properties, lets
call it property semantics. For a property semantics to have more flexibility
it would be great to have ability to specify not only constants, but to use
variables as well

> Project: Commons JEXL
> Issue Type: New Feature
> Affects Versions: 3.1
> Reporter: Dmitri Blinov
> Priority: Minor
>
> Now we have a possibility to access an object property by specifying either
> {code}object.property{code} or {code}object."property"{code} expression, but
> not {code}object.`property`{code} expression. Since interpolated strings can
> be used anywhere in scripts as ordinal strings, it would be logical to allow
> them to be used in property access operators too. It would allow to have the
> property name not necessarily to be a constant, but to be evaluated without
> using the array access operator, since property access operator and array
> access operator could be implemented (overloaded) differently for the object.
