I'm not clear what you're asking, but this is legal Ada. Bar gets its bounds 
from its initialization expression. I presume that you want to call it with

Foo (A => Left.Data & Right.Data);

which is also legal. If the only reason for Foo is to have a shorter name, you 
can also do

declare
    Bar : String := Left.Data & Right.Data;
begin
    ...
end;
