However type conversion is another beast. If I designed the language I
would support ad-hoc subtypes (ones established dynamically in some scope
without implementation inheritance). E.g. in some context one could make
Integer a subtype of String and just write:
I : Integer;
...
Put_Line ("I=" & I);
Static type relationships, even with MI and MD support, are not flexible
enough to handle cases like I/O, containers etc in a generic way. You need
an ability to create a virtual parent for unrelated types later on to be
able to have a class of these types (on order to define operations handling
instances from this class).
