OK x not xx.

The doubling of operators is confusing.

Are you sure you didn't want the x (string repetition) operator, instead of xx (list repetition)?

I'm not sure why the elements of the expansion are padded with a trailing space in one context but not in another.

print calls .Str, say calls .gist.

I wasn't sure whether this is the specified behaviour.
It is.

If it is how can it be turned off?
Call .Str or .gist on the argument to print/say as needed.

I suspect that the problem will be resolved by using the x operator instead of xx, however. :-)
