Today I learned that natives can be forwarded and this can be used to deprecate natives and add replacements for them without getting a deprecation warning inside the replacement function:

forward DeprecatedNative();

stock NewFunction()
{
? ?return DeprecatedNative(); // no warning here
}

#pragma deprecated Use `NewFunction` instead.
native DeprecatedNative();

main()
{
? ?DeprecatedNative(); //?(warning) function is deprecated (symbol "DeprecatedNative") Use `NewFunction` instead.
? ?NewFunction();
}
