Is there anything in the standard library for building an iterator from a list of iterables?

[Mark]

It seems it’s: flatten().iterator()

And how about for building an iterator for a single item? Something better than listOf(item).iterator()

[ilya.gorbunov]

Better to convert a list of iterables to a sequence of iterables, then call flatten().iterator(). Otherwise flatten invoked on a list will materialize list with all flattened elements — perhaps not what you wanted.

That’s much better, thanks!
