Quite often I see constructions like this:
foo({one:1,two:2});
so call of function with single parameter - object literal.
Idiom named "Poor man named arguments passing"
Idea is to extend existing JS/ES syntax calls to support
simple form of the call above:
foo {one:1,two:2 };
Semi-formally that syntax looks like:
function-call:
<name-token> '(' <parameter-list> ')' // existing form
<name-token> <object-literal> // proposal
This syntax extension will not break correct pre-ES6 code
as far as I can tell. But I am not sure about new ES6 arrivals.
In fact we can add even more generic form of function call:
foo 1,2,"three";
that is an equivalent of foo(1,2,"three");
In this case grammar may look like:
function-call:
<name-token> '(' <parameter-list> ')' // existing form
<name-token> <parameter-list> // proposal
Where <parameter-list> is comma ',' separated list of expressions.
Just to reduce that bracketing noise in syntax.
