We've already had a suggestion for [[]]@5 and that should deal with that
issue. Steven is proposing "multiply by copying" as an alternative to
"multiply by referencing", so an alternative multiplication operator
should fit that correctly. Steve, I don't want to speak for you; can you
confirm or deny acceptance of the matmul operator as a better spelling?
I thought that ** would be less controversial than @ since that's much
newer. Silly me.
Personally, I don't care much either way. Probably a microscopic
preference for @ over ** since it is shorter, but not enough to matter.
@ requires use of the weaker/shorter "ring finger" on (for me) the
weaker left hand.
On my UK keyboard, @ is on the right-hand side.
** makes use of the stronger right hand, and longest finger so less a
stretch. And the timing for the second * isn't that much.
Let me play devil's advocate... and propose a simple change, with no
new operators...
sl = [] * n #current behavior
dl = n * [] #deep copy behavior
Both orders are currently valid, and do the same thing, so a change
would break someone's code.
