I used
if ($var(x) != null) { ... }
in one of the routes, and tried to run Kamailio server. The server exited with an error. I did not know why.
Once I changed it to if ($var(x) != $null) {} the error went away. I missed $ infront null. I think it is hard to trace such problems once a large chunk of logic is written since many of us come from C++ and scripting background where $null is not a common practice.
Also if I tried to use if (!$var(x)) { ... } Kamailio tries to convert the value of $var(x) to integer. prints WARNINGS in the log when the $var(x) consists of a string.

I understand the pain. One thing I found was vim syntax highlighting and there was a thread before that I saw for midnight commander syntax also. I have not tried either but maybe it could help in syntax for your needs
