yes, sure; just using help as an example of a command.

Going forward I would assume "create-datasource", "remove-datasource", "list-servergroups" etc. would be defined which
would be much more convenient than having to tabcomplete/guess the longwinding (but useful for raw access) operation "api".

using / to distinguish that sounds like a perfect way for me ?

I.e. possibly simply have an "eval" operation and "/" be its alias...

eval subsystem=web,connector=http:read-attribute(name=bytesReceived)

or 

/ subsystem=web,connector=http:read-attribute(name=bytesReceived)

sure - or like a setcontext/sc or setprefix/sp maybe ?

[]
sc subsystem=web
[subsystem=web]
/connector=http:read-attribute(name=bytesReceived)

?

not sure if its worth the complexity skipping typing a single / for the raw access.
but you could toggle it by using an empty / as a toggle between these.

Once there are more highlevel commands/shortcuts I really don't think the raw
access would be used much IMO where prefixing with / wouldn't be a big issue.
