parameter list is sometimes called the operator,
and the terms of the term list are called subterms.
EG, \ ["foo","OPID"; "1,"n"\],\[\["bar","OPID"; "a","s"\],\[\]\] Wiki Markup
Shorthand : use {,} to indicate parameter list with and (;) for subterm list
EG: {foo:OPID, 1:n}({bar:OPID, a:s}())
...
If either list is empty leave off {} or ()
EG: foo{1:n}(bar{a:s})
If both lists are empty, ie just and OPID then include ()

EG, nil() == \ ["nil":OPID\],\[\]
the parameter list can be empty, eg {}(foo())

or most degenerate case : \ [\],\[\] == ()
