NAME

threads::tbb::concurrent::item - lazy deep copy slot

SYNOPSIS

  use threads::tbb;

  #my $scalar :concurrent;  # TODO
  tie my $scalar, "threads::tbb::concurrent::item";

  # this works:
  $scalar = "foo";
  my $item = $scalar;  # safe

  # never:
  $array[0]->mutate;

DESCRIPTION

The concurrent item is a single slot which is not duplicated when passed between threads. It is a way to access the lazy deep copy mechanism used by threads::tbb::concurrent implementations, free of the container.

It does not correspond to any formal TBB API, and should not be considered thread-safe when used in isolation.

This API should be considered EXPERIMENTAL. It probably needs altering to be safe, at the very minimum by cloning objects on the way in.
