Sorry that I didn't answer until now. I forgot to activate notifications for discussion... :-(

The OCL let-Expression is supported by USE:

let i:Integer = 5 in i * i

The keyword def is not supported, but you can define query operations using the syntax shown in this example:

class Lemon
operations
  squeeze(i : Integer) : Integer = i + 1
end

Here, i + 1 is the (query) body of the operation.
