FEATURE(delay_checks) by adding a literal n as a third argument:
FEATURE(`delay_checks??, `friend??, `n??) ?†? V8.12 and later
FEATURE(`delay_checks??, `hater??, `n??) ?†? V8.12 and later
This n turns off backward compatibility (the ability to ignore the old syntax) and
causes the old syntax to produce an error. This is a good way to check to be sure
your conversion was good.

file:

FEATURE(compat_check)
Once this is enabled, you can then add entries such as the following to your access
database (note that the <@ > is literal):
