A small request here:
I needed to know what var::toString will return for various types of vars. Sadly there is no documentation for this member function, so I had to got through the source code to find out what it does in the various cases. A quick enumeration of what the string returned will contain for the various types of vars would be a great enhancement for the documentations in my opinion.
Side question: As there is no documentation of that function, can I still expect it’s implementation to stay as it is so that I can rely the current behaviour in my code?
