R7RS says that this procedure and a few others were added in order to
round out the sequence operations.
The R7RS variant of this procedure terminates early if the vectors are
not the same length, but the R6RS variant requires that all the
vectors are the same length. Additionally R7RS makes it an error to
mutate any of the vectors.
This procedure can raise exceptions with the following condition types:
- &assertion (R6RS)
The wrong number of arguments was passed or an argument was outside its domain.
In particular, the
should all have the same length and
should accept as many arguments are there are vectors.
The assertions described above (except for the length requirement) are errors.
Implementations may signal an error, extend the procedure's
domain of definition to include such arguments,
or fail catastrophically.
It is an error for
to mutate any of the vectors.
This procedure first appeared in R6RS. It was later also added to R7RS.
