Just out of curiosity, what do you think a procedure type is?

In a language like Modula-3, conceptually, a procedure declaration is a
declaration of a constant of the appropriate procedure type, and one can
pass procedures as parameters, store procedures in variables, invoke
procedures stored in variables, and the like.  A compiler will probably
implement all this with pointers, but you don't have to explicitly
dereference pointers yourself, just as you don't have to explicitly
dereference pointers when passing arguments by reference in Pascal or
FORTRAN.  Do you really like typing so many "&"'s and "*"'s in C?
