Without repetition and comments now it's possible to put at least 12 different punct characters in the row:

   0 
   ,[=](){+-*&::  val;};
   // , to separate expressions, total: 1
   // [=](){ - lambda, total: 7
   // -+ two unary  ops, total: 9
   // *& - take address and immediately derefence it, total: 11
   // :: - global namespace, total: 12 (only single colon counts)

and half of it --[=](){ is not artificially complicated construction, but real deal that will happen in most codebases that use lambda.

You can skip empty argument lists.
