Implement ternary quotes sequence """ to avoid escaping in the shell

I think it would be great to have ternary sequence """ which will allow us to not escape quotes in the string.

for example when we want to pas argument to command which contains quotes, this operator could be used:

cmd --param """first " second " third " quote"""

Now you have to input this:

cmd --param "first \" second \" third \" quote"

This could be useful if user want to input parameters with lot of quotes.
