I think so. But the scope where these side-effects take
place is important as well. In your second example below
the side-effect is restrained to the subs scope. Th

Because I can't think of

In other words, I think we could get proper constraint programming if a

to be wrapped inside of an eval and the code would be more bug-prone.

I hope that is a deep readonly? In other words, if $_.position returns
an array reference, can I mutate a value in that reference and the
state of $_ is thereby changed

See S12:

as it looks like we can get declarative style constraint programming
for free:
subset Crosshair of Point where { $_.inside_of($t

Anyone have any idea why Google is not indexing the official Perl 6
documentation at perlcabal.org/syn? I checked the robots.txt and it
looks fine:
http://www.perlcabal.org/robots.txt
But the search box on http://www.perlcabal.org/syn/ returns nothing.
