for (my $i = 1; $i <= 3; $i++) { say $i; }

prints 2 instead of giving an intelligent error message that one should use loop
or better yet for 1..3 -> $i { }

A warning, surely? As far as I can tell, the above is perfectly legal
code. Presumably "say $_" would also yield 2, since I gather the for
is looping over ($i).

Since the for-loop is legal syntax, you should try to bug Larry to make
STD.pm emit a warning, then implementations will follow; since it's not
yet specced, I'll stall this ticket.

$ perl6 -e ' for (my $i = 1; $i <= 3; $i++) { say $i; }'
2

$ perl6 -e ' for (my $i = 1; $i <= 3; $i++) { say $i; say $_ }'
2
1

So the "++" is applied before the loop body but after the assignment to $_

History will have to record that the greatest tragedy of this period
of social transition was not the strident clamor of the bad people,
but the appalling silence of the good people.
