range syntax for C

[t.l.hansen]

<< How about using a double colon like this 1::10

< Except it might do screwy things if C++ ever wanted to adopt case ranges.

<< This also looks fairly natural in a case statement:
<< 
<< switch(x)
<<   {
<<     case 1::10 :  do_this(); break;
<<     default :     do_that(); break;
<<   }

Would it really do screwy things? Because of the maximal munch rule, a new
token "::" would have to be parsed as "::" and not as a ":" followed by
another ":".
