Sorry, no it can't. From S4
(http://dev.perl.org/perl6/doc/design/syn/S04.html#The_repeat_statement):
"Unlike in Perl 5, applying a statement modifier to a do block is
specifically disallowed
Which if crammed together the way you wrote it, turns into:
do {do {say 1 if 1} if 1} if 1;
Or perhaps you like this even better:
do{do{say 1 if 1}if 1}if 1;
I find that hard to guess. I personally think the statement is confusing
anyhow, with or without whitespace. Besides, stacked "if"-statements
really don't make any sense. We've already got "and" for that! :)
say 1 if 1 and 1 and 1;
Oh, and 1 is always true. So you could just write:
say 1;
Which seems like a great improvement.
It may be more useful to discuss this issue using less contrived
examples. :)
