| ,-,"FooOrBar types mean that the argument's type was Foo, but the value also fits into the more specific Bar type.",,,,,,,, |
| ,,"This possibility should only be utilized as a last resort, to keep the method selection stable (always selects the same method) for Foo-s regardless of the actual value.",,,,,,,, |
| ,,"This is why the column of Bar-s tends to use higher costs than the less fitting columns that are, however, also selectable for higher values of type Foo.",,,,,,,, |
| ,-,"Between same-price conversions the one in the leftmost column (i.e., the smallest type) wins. This is realized in the Java code generator.",,,,,,,, |
