:Sure. If the access value denotes a record value, you don't have
:to put ".all" to access the record's fields:
:
: F := Access_Value.all.Field;
: F := Access_Value.Field;
:
:This requires different syntax in C ("@" and "." versus "->", IIRC).
Doesn't sound nice. :)
:In a case like this, it's unlikely you are making a mistake, so Ada
:assumes you want the implicit ".all".
I guess I was aware of implicit dereferencing. What I didn't appreciate
was the value of combining it with formal access-parameters.
:On the other hand, mis-using a pointer to a scalar is a common
:error, so Ada doesn't infer any de-references -- you have to do
:them manually.
Wasn't aware of this restriction - makes sense.
