Okay, believe it or not, I read all of this back and forth, and I'm not going to join one side or the other. My takehome from this is that "Standard Perl 6" has three categories of operator:
- Operators that require serial semantics, such as &&
- Operators that require parallel semantics, such as junctions and hyperoperators
- Operators that mandate neither, because we obviously don't all understand the problem yet
However, I would point out that "Standard Perl 6" exists only down to the first declaration that mutates the language. So it would be entirely reasonable to have a pragma that gives whatever hints it it is felt might aid the compiler in whatever activity the compiler chooses to engage. If it turns out that giving the compiler more information about execution order helps rather than hinders the optimization of parallel routines, I'm sure that such a pragma will become very popular, possibly to the extent of being incorporated into the base language. Otherwise, not.
