In general we seem to support concatenation of multiple dates with strings but not addition of multiple dates.
Observed behavior: uassert if an attempt is made to add two dates as part of constant folding, even if the folded value would be unused because of a non constant string value.
Expected behavior: No uassert in this case.
Test:
c = db.c;
c.drop();
c.save( { x:' ' } );
// No uassert when concatenating multiple constants.
printjson( c.aggregate( { $project:{ a:{ $add:[ new Date(), ' ', new Date() ] } } } ) );
// uassert when concatenating date constants (constant folding) and a non constant string.
printjson( c.aggregate( { $project:{ a:{ $add:[ new Date(), '$x', new Date() ] } } } ) );
