In a number of ways, r behaves as if it were that list, but r is
definitely not that list:
 >>> r = range(10)
 >>> type(r)
 <class 'range'>
 >>> l = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
 >>> type(l)
 <class 'list'>
 >>> r == l
 False

Citation needed? I can't speak for every version of BASIC ever, but the
ones I used had separate namespaces for numeric variables and string
variables: A was a number, A$ was a string, and never the twain shall
meet. That's strict typing.
