Actually, would be a bit slower, as you get the variable address evaluated in the At once. Your version evaluates it twice (and in composition example, access the outer container twice too).

well, that depends of compiler code... usually "modern" compilers take care of avoiding double access when unneeded.

Only if everything is inlined Smile

Just a last word, I *don't* think to propose you to change from pick_ to refcounted arrays (usually I hate when someone writes to me of changing core parts of my code !), I'm just curious of performance differences and possible caveats of this kind of solution.

OK. I like diggin' in this stuff.
