Regarding your first suggestion; quite some of my scripts use dots in alias names, and this would break all of them. I'd rather see $myalias().prop being supported, ie. just the parentheses and no need for a filler. A detail maybe, but an important detail.
About the second suggestion, I believe that the general outcome of the last discussion about it was that you can achieve the same by just /return'ing a list of tokens. I'm not saying it's a bad suggestion, though...
