#1Allow multi-quoting
Currently, you are allowed to write e.g. "[] 1 : 2 : ,sin map" but you can't quote something twice, like ",,somefunction" or so.
You can work this around by defining ", somefunctionwrapper ,somefunction" and then write ",somefunctionwrapper" instead of ",,somefunction"; but that's not that cool.
