I have not had time to look up whatever it is that you are doing. What I
know is that there are a finite number of ways which can be used to
interact with an argument and none can be safely (i.e. without errors)
used on all input (discounting pathological unbalanced parentheses) with
the sole exceptions of stringizing (which you can always do) and token-
pasting to a placemarker (which you can always do) neither of which yield
results which are detectable for this purpose.
Without having to looked at precisely what you think works, I suspect that
you are doing something that should produce errors with some types of
input but doesn't because the particular preprocessor(s) that you've used
are permissive instead of strict.
If you show what you are doing here, I can take it apart to show where it
doesn't work. Pardon if you have already shown that and I missed it.
