Perl does have a defined order of evaluation;

Do you know something that neither p5p nor comp.lang.perl.misc knows? Order of evaluation has been discussed recently on both forums, and noone one these forums has been able to show that Perl has a defined order of evaluation. Please quote the relevant parts of the documentation that define order of evaluation in general. (Order of evaluation is defined for &&, ||, and, or and comma in scalar context, but not generally).

How can I trust
print 5+1;
always prints 6, and not 5 (and a warning)?

Precedence garantees that. Just like C, Perl does have well defined precedence and associativity rules. But neither language has a defined order of evaluation.
