Hi Michael,

you should realize that while that seems to be simple example, it's a
very unusual thing to have in a flow graph :)

That said, you can create a vector source (which you usually don't), and
initialize this with something like 'range(5)' and set it to repeat.
Remember that in GRC, any initial values for your blocks don't have to
be numericals, but simply any valid Python code, so even a list
comprehension is fine (i.e. anything that returns a vector).
