I'm thinking about adding convenient isInstance method to TypeInfo.
On ClassInfoImpl/JavassistTypeInfo it would use getType::isInstance,
but on PrimitiveInfo it would still look into progression.

The method would hide simple impl detail.

TypeInfo ti = ...;
Object value = ...; // not null

//long version
TypeInfoFactory tif = ti.getTypeInfoFactory();
TypeInfo other = tif.getTypeInfo(value.getClass());
boolean isInstance = ti.isAssignableFrom(other);

// short
boolean isInstance = ti.isInstance(value);

// where this doesn't consider progression
boolean isInstance = ti.getType().isInstance(value);
