I just uploaded a new version of Template::Alloy that has this support. You
will have to set STREAM => 1 to enable it. It was actually very simple and
quick to implement - but writing the tests and edge cases took a bit more
time.

use Template::Alloy 1.010;
my $ta = Template::Alloy->new(STREAM => 1);
my $template = qq{Here we go
[%- FOR a IN ['A' .. 'C'] %]
[%- FOR i IN [1..3] %]
[% sleep %][% a %] - [% i %]
[%- END %]
[%- END %]
};
my $vars = {
sleep => sub { sleep(shift || 1); ''},
};
$ta->process(\$template, $vars) || die $ta->error;
