"iota" is already present with the same semantics in 1.25 languages:

For me, a Google search for "C++ iota" only returns discussions about
whether such a function actually exists in the STL. Is it really in the
standard?
It's not in the standard (and I haven't claimed so). It's commonly
present as an extension.
Anyway: Looking at the definition of ïota in Phobos, it simply seems to
be a slicing operation with a stride. Most intuitive to me would be to
rename the function to "slice" and the option step to "stride"?
iota(0, 10, 2) generates the numbers 0, 2, 4, 6, 8.

The name "stride" is currently used by a range adaptor that takes a
range and walks it with a given stride. stride([1, 2, 3], 2) generates 1
and 2.

BTW stride iterators are mentioned by Stepanov:
