I don't think your history is correct.  Or perhaps
I misunderstand your use of the term "significant
influence".  Certainly the constructs that Samuel
listed (DO/LOOP, FOR/NEXT, BEGIN/WHILE/REPEAT)
were in other languages before they were in some
incarnation of Forth.  I believe that DO/LOOP
was in a Forth Chuck Moore wrote (or worked on).
I know for a fact that FOR/NEXT is.  (It's in
ColorForth afterall, and it was first seen in
cmForth if MY history was correct).
