Clarification

Maybe you need to elaborate some more on what you mean.

rest parameters do exist:

p:=proc(a,b) a*b,_rest end proc;
p(8,9);
p(8,9,s,y,i,o);

#Another example:

f:=x->x^2*`*`(_rest);
f(3);
f(3,4);
f(3,4,5,6,7);

#There is also the sequence modifier

g:=proc(s::seq(anything)) local S; S:=[s]; S[1]*S[-1] end proc;
g(3);
g(3,4,5);

But maybe that wasn't what you meant?
