"::" doesn't work inside an identifier.

[Joseph Ryan]

According to the CVS log for /languages/imcc/imcc.l, "::" is now
allowed inside an identifier name.  However, when I try to create
an example like:
   .sub foo::bar
       end
   .end
It gives the error:

   error:imcc:parse error, unexpected LABEL, expecting IDENTIFIER

Is this a bug, or am I misunderstanding something?
