The whole point of variants is that it allows you to get around  
compile time type checking. If you want compile time type checking,  
don't use variants. Giving a warning for each "non-variant + variant"  
operation which might fail would give a warning for pretty much every  
such operation, since there are virtually always combinations which  
may not give a valid result.
