(same? ..args) args: two or more arguments (any type) returns a bool
#t if all of its arguments share the same identity.
Each successive pair of arguments is compared in turn. If any of the comparisons are false, the function returns early.
Numbers and characters are compared using
#nhas the same identity as
#thas the same identity as
#fhas the same identity as
All other values are references. Two references share the same identity if they belong to the same primitive type, and refer to the same memory location.
