@n8sh created dlang/druntime pull request #2770 "Give TypeInfo_Class/TypeInfo_Interface.isDerivedFrom like C#/Java isAssignableFrom" fixing this issue:

- Fix Issue 20178 - Add TypeInfo_Class/TypeInfo_Interface.isDerivedFrom

  Equivalent to C#/Java isAssignableFrom with the argument swapped with
  the receiver. Naming the method "isAssignableFrom" would be more
  familiar to people coming from C#/Java but is potentially misleading:
  "alias this" and overloadable opAssign mean that this would not
  actually indicate whether values of one type could be assigned to
  another.

  Fix Issue 20178 - Add TypeInfo_Class/TypeInfo_Interface.isBaseOf

  Equivalent to C#/Java isAssignableFrom. Naming the method
  "isAssignableFrom" would be more familiar to people coming from C#/Java
  but is potentially misleading: "alias this" and overloadable opAssign
  mean that this would not actually indicate whether values of one type
  could be assigned to another.

  Adding qualifiers to rt.cast_ functions.
