Hello,
I'm seeking for some information about the things stored inside a modemap.
It looks like the structure is approximately as follows.
((
(NAME ARG1 ARG2 ... ARGN)
(TYPE-FOR-NAME)
(TYPE-FOR-ARG1)
...
(TYPE-FOR-ARGN)
)
(T NAME)
)
However, there seems to be a difference between category constructors
and domain constructors in terms of using |#1| vs. |t#1| inside the
"TYPE-FOR-ARGi" part.
It seems that |ẗ#1| also refers to the first parameter of the original
constructor (NAME). Is that true? Why is there a use of |ẗ#1| if |#1|
would suffice?
