Improve the syntax of the new API to prevent unintuitive behavior #208

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
One of the nice things about the new API is that it lets you easily modify 
nodes, e.g.:

foo["x"] = 5;

However, this currently causes the following behavior (see Issue 207):

Node a;
a = foo{"x"];
// ...
a = foo["y'];  // <-- this line is the same as foo["x"] = foo["y"], which 
modifies the document

This is unintuitive. It would be nice to support the former behavior but 
prevent the latter.

May be a solution to have an operator= which applies only to const objects and 
does not modify the object?

There shouldn't even be an overload to operator= on const objects - please see 
my comment on Issue 285 (which I just merged into this).
