I thought about this yesterday but maybe overloading the method is better.
Because this way the function must have to be passed as of expecting an id
argument, even if the id argument for ldm() is optional.
I just haven't added yet because of lack of usecase. :-)
But thanks!!
This DSL is saving me a lot of coding, even if is not actually a DSL, but a
"way to go". :-)
