[REBOL] Re: Core 2.6 - Last minute requests - take your chance! - shares

That would be cool.
I think 'b would have to be a new datatype.
One that stored its own index and length
and imposed its head and tail on the series.
But what happens when elements are removed
from 'a that are also in 'b ?
Should the length of 'b be reduced?
Rebol would have to keep track of all the shares
and update them when the original series is modified.
This would slow rebol down a fair bit, I reckon.
Otherwise, the length of 'b wouldn't be updated
and you could get the situation where the length
of 'b is greater than the number of elements that 'b
But that might just be a totally acceptable situation too!
Maybe the user could be in charge of updating the length
of the share when it seems appropriate.
