-This might be good idea / convention.
+Yes, this is a good idea / convention.
 
 ## Q. Can we make parameterized goals resolution during parsing? We might need to know the number of params for a goal which is not available yet, since goal may come later.

 ## Q. Allow listing PG?
-No.

+No. But we list “instantiated” goals instead.
 
 ## Q. Loops detection.

 ## Q. What can be `@args VAR`?
 Only:
-- what’s in `@define`
+- what’s in `@define` (not now, maybe in future)
 - any VAR in `@params` of this goal
-  All other cases must cause error.

 ## Q. Mechanism for "instantiation"
 
 Also here. Need to adjust `-d` option. Should list instantiated goals in form
 
-- `pg1 @args 'hello'`
-- `pg2 @args 'hello' $'with \''`
+- `pg1@hello`
+- `$'pg2@hello@with \''`
