If it sucks to write async code, just use generators and write a sync code.

--I will go out on a limb here and say it sucks to have to write a bunch of async code to load data in node. Many times we know exactly what we want to load ahead of time. Why can't we just declare all the things we want to load and then load it all at once? For example, with two mongo collections:loader.add( {contacts : {fields : [ 'firstName', 'lastName' ],where : { group: { $in: [ 'business', 'personal' ] } },sort : { lastName : 1, firstName : 1 }},groups : {fields : '*',where : { label: { $in: [ 'business', 'personal' ] } }}} );And then load them all at once with one simple async call?loader.load( function( err, payload ) {console.log( payload.contacts ); // array of contactsconsole.log( payload.groups ); // array of groups} );We have found this paradigm especially useful when simply relaying JSON data to a client. Wrote a song about it. Here it goes:Anybody else experimenting with declarative approach to loading data?David BEck--
