The use of bind in Ticker.h is prone to type inference failure (#6129)

Browse Source 
* std::bind has issues with type inference, use lambdas whereever possible.

* Fix indentation.

* More descriptive placeholder name in lambda expression

* Use formal argument names for remaining currying placeholders
