Isn't that "Danger, Will Robinson"?
I certainly agree with this advice. One thing that always stopped me
short in my tracks was code with constructs such
... + My_Type (3) - ...
apparently written by people who thought that "3" has type Integer (or
perhaps used a compiler with that "feature").
However, is there any reason to write
Assert_1 : constant := Boolean'Pos (Assert'(Integer'Size = 73) );
rather than
Assert_1 : constant Assert := Integer'Size = 73;
? Are there compilers that won't check this during compilation?
