The ultimate problem is that the operator "%" is used in two contexts:

patsubst etc. In this situation those two operators conflict and

Ah, that makes sense.
Is there any validity to the argument that SECONDEXPANSION implies
"second variable expansion", which implies that the variable expansion
would happen before the pattern substitution (even for the purposes of
creating variable names using the pattern)?
In other words, does it make sense to say that if I use SECONDEXPANSION
I am implicitly saying that I want variable substitution to happen
before pattern replacement? That's how I interpreted it but others may
think differently.
If this strict ordering is not desired, then maybe it makes sense to add
a substitute character that can be used in place of % for either the
pattern rule or the function; I would think that allowing an alternate
character inside the function would make the most sense since changing
the pattern rule character would result in a different character used in
the rule target than in the rule prerequisite.
Thanks,
