- * <p>Note that as of this writing, this method is only used when

- *
- * <p>Why's this needed, how it works: Overloaded method selection only selects methods where the <em>type</em>
- * (not the value!) of the argument is "smaller" or the same as the parameter type. This is similar to how it's in
- * the Java language. That it only decides based on the parameter type is important because this way
- * {@link OverloadedMethodsSubset} can cache method lookup decisions using the types as the cache key. Problem is,
- * since you don't declare the exact numerical types in FTL, and FTL has only a single generic numeric type
- * anyway, what Java type a {@link TemplateNumberModel} uses internally is often seen as a technical detail of which
- * the template author can't always keep track of. So we investigate the <em>value</em> of the number too,
- * then coerce it down without overflow to a type that will match the most overloaded methods. (This
- * is especially important as FTL often stores numbers in {@link BigDecimal}-s, which will hardly ever match any
- * method parameters.) We could simply return that number, like {@code Byte(0)} for an {@code Integer(0)},
- * however, then we would lose the information about what the original type was. The original type is sometimes
- * important, as in ambiguous situations the method where there's an exact type match should be selected (like,
- * when someone wants to select an overload explicitly with {@code m(x?int)}). Also, if an overload wins where
- * the parameter type at the position of the number is {@code Number} or {@code Object} (or {@code Comparable}
- * etc.), it's expected that we pass in the original value (an {@code Integer} in this example), especially if that
- * value is the return value of another Java method. That's why we use
- * {@link NumberWithFallbackType} numerical classes like {@link IntegerOrByte}, which represents both the original
- * type and the coerced type, all encoded into the class of the value, which is used as the overloaded method lookup
- * cache key.
- *
