Remember the story that Ken Thompson had written a
language called "Bon"
which was one of the forerunners of "B" which then led to "new B" and
then
to "C"?
I just found Ken Thompson's "Bon Users Manual" dated Feb 1, 1969, as told
to M. D. McIlroy and R. Morris
in Jerry Saltzer's files online at MIT.

There was clearly a lot of cross-fertilization between early APL systems
and Bon. (APL was the first computer language I dug deeply into.) Some
of the common elements are the interactive execution environment,
untyped variables, and automatic application of builtin functions (like
+) across all elements of arrays.
