Return @code{#t} if @var{x} and @var{y} are the same type, and their
contents or value are equal.
The Scheme procedure returns @code{#t} if all of its arguments are the
same type, and their contents or value are equal. The C function is
similar, but takes exactly two arguments.
For a pair, string, vector, array or structure, @code{equal?} compares the
contents, and does so using the same @code{equal?} recursively,
