Very interesting.
I think he documentation should be expanded to detail this. Multiple
parameters to operators are only documented in a few operators, but if I
read this correctly they can work on operators in *general*?
If general you may expect this to work ```{{{ [title[tid1],[tid2],[tid3]]
}}}``` it does not.
or {{{ [all[current]get[caption],[description]] }}}``` it does not.
