which included tuples, but after an initially warm reception, TC39
settled down to more incemental moves, and binary data emerged.
We've been thinking along the following lines since then,
apologies for brevity:
With new Uint32Array(4) you get a reference type instance. Just as
with typed arrays today, but same goes for structs as for arrays.
With Uint32Array(4) -- note lack of 'new' oeprator -- you would
get an immutable value type, which could be stack allocated if
escape analysis allows. This is for the VM to worry about. It's
the JS way.
I like where this is going. But how did the array returned by
Uint32Array(4) get initialized?
Same as with typed arrays today:
js> a = Uint32Array(4)
({0:0, 1:0, 2:0, 3:0})
Could these be the same as the ParallelArrays used by rivertrail? They
can be safely shared between workers for the same reason they can be
safely shared between threads within an event loop.
This seems possible, but I defer to Dave, Niko, and Rick.
