Yes, that is the key feature. On top of that:

1. Asynchronous aborting of the running script with data cleanup.

2. External loadable module/packages for it written in Ada

3. Means to maintain the process state between calls to the script. For 
Python it is resolved by returning an object from the script. The object 
is then passed as an argument by the next call. For an Ada script one 
could do it better, as a kind of "library package".

BTW, there is another project alike AdaScript:

    http://www.pegasoft.ca/docs/sparforte12/doc/ref_adascript.html

which also lacks the above. It is a shame that GPS uses Python for the 
purpose. I am using Python too, because presently nothing is better. I 
considered Lua and Julia, but neither were usable.

Having yet another shell, is not interesting. From my experience no 
regular task deserves writing it in a script. Each time I do this in 
bash etc, I get punished for. When I am lucky I rewrite that in Ada. I 
am too lazy to do this from the start always hoping it would end 
differently. When I am not so lucky I am stuck for years with 
maintaining the crap which periodically stops working.
