Subject: [PATCH] Support filters being call chained

Previously filters were not treated the same as variable, as a
result it was not possible to call the result of a filter. Since
filters are treated as regular variable and therefore can be called
any number of times, this change was necessary to allow them to be
parsed the same way.
