I'd prefer you named your parallelization pragma parallelizable or such. I have similar interests in this flag except mine would be for explictly altering the execution order of blocks to allow pipelines like grep { ... } map { ... } ... to present a low profile instead of having to fully compute each section before passing on to the next operation.

Using the parallizable pragma I can transform the following code. The benefit is I only have the minimum amount of intermediate results present at any given moment rather than the maximum.

{
  use parallizable;

  @ary
    = map { ... }  # block 1
    = grep { ... } # block 2
    = map { ... }  # block 3
    LIST;
}

{
  for ( LIST ) {
    for ( do { block 1 } ) {
      next if not do { block 2 };

      for ( do { block 3 } ) {
        push @ary, $_;
      }
    }
  }
}
