  I found a method. It may not be the fastest possible, but at least it works.

#macro Is5DVector(V)
  (strcmp(vstr(5, (V=V), "", 0, 0), "11111") = 0)
#end

#declare V1 = <1,2,3>;
#declare V2 = <4,5,6,7,8>;

#if(Is5DVector(V1)) #debug "yes, " #else #debug "no, " #end
#if(Is5DVector(V2)) #debug "yes" #else #debug "no" #end
#debug "\n"
