Hi,

this is the output for compiling a diet template 

Error: inout method vibe.data.bson.Bson.opIndex is not callable using a mutable object

//product.dt 
...
   - foreach( field; schema.fields)

schema is a Bson object obtained from mongodb using findOne();
I get the same output from schema["fields"];

But the same code works in a normal .d file

Any ideas?
