Issue

Failure

The dictionary constructor literal does not work inside expressions and in a declare statement

Steps to reproduce

# example 1: ternary
$meta = isset(meta) ? meta : {};

The error in this case:

Error parsing filterx expression: syntax error, unexpected '{'

In /usr/share/syslog-ng/include/...
88        filterx {
89          $vars = vars();
90---->     $meta = isset(meta) ? meta : {};
90---->                                  ^
91

# example 2: declare
declare meta = {};

declare meta = {}; now works.
