A12: Mutating Methods and hyperoperators

[Matthew Walton]

I know these were discussed to death not that long ago, but reading 
Apocalypse 12 I had a query I couldn't remember if it had been covered 
before or not, and I certainly don't recall seeing it in the Apocalypse, 
although I've not read the entire thing with as much attention as I 
might like yet (it's great work though).

So, simple query. I know I can do

@things».method();

But can I do

@things».=method();

which would presumably be the same as

map { .=method() } @things;

And if I can't do it, why not? I think I should be able to do it, but 
it's entirely possible I've missed something, because I usually have.

Thanks

Matthew
