used previous is becoming more common because it allows you to
set multiple stash variables in one line. For example:
- $c->stash(template => 'hello.tt', foo => 'bar',
+ $c->stash(template => 'hello.tt', foo => 'bar',
another_thing => 1);
You can also set multiple stash values with a hashref:
- $c->stash({template => 'hello.tt', foo => 'bar',
+ $c->stash({template => 'hello.tt', foo => 'bar',
another_thing => 1});
