It would still be silly if someone who wants to reinvent this wheel
doesn't bother to look at what DEC did.

Yeah, I think so.  Strings, for example.  Cobol, PL/I, Algol,
Fortran-77, Snobol, etc., have string types and say what kind of
operations can be done on strings.  C says that a string is terminated
with a '\0' byte.  Instead of assigning a null string to a target,
C programmers assign a '\0' byte, so the implementation of C library
routines can never be speeded up.  For other languages, improvements
are often made to implementations.
