New feature request: we often make collections dynamically based on some naming convention, and I'd like a way to specify that any new collections whose name matches a regexp condition should automatically get a particular set of indexes when created.

I'd envision this as being specified by a hash where the key is the regexp and the value is an array of normal index hash specifications to add.

Something like:

db.autoIndexCollections( { "/page_logs_%d

/": [

,

] } );

would create two indexes on date descending and source ascending for a newly created page_logs_201108 collection.
