And again, this leads me to question - how about Macro's? So, it comes
point that macros defined in AEL are unusable from anywhere except
AEL, right? And as there is no argument support for GoSub in 1.4 there
is no way how it's possible to upgrade from 1.4 to 1.6 without any
configuration change. Now I see that app_macro_wrapper should probably
include handling of AGI MACRO call, and I start to doubt is that the
correct way. Maybe another compatibility switch for AEL parser to not
use GoSub's internally. So people could upgrade to 1.6, and update
configs later.

No offense, but this just breaks statement i heard some days ago about
"Using non-deprecated functionality should not require changing config
between major versions".
