I'm not a fan of building in every function that can (as you just
showed) be written easily in a couple lines of Python.  If something
like this ever is built in, it certainly won't be inclusive of the
endpoint -- that's too jarringly different from range().   And if
something like this ever is built in, it will also grow ugly variants
to increment by hours, minutes, months, years, weeks, quarter-hours,
...

I've noted before that I've not enountered another language community
so eager to bloat the language with things they can trivially do on
their own.  What's up with that?  I personally find Python functions
pretty easy to write -- even four-liners <wink>.
