[REFACTOR] Refactored some of the generic-lambda capturing code.
Employed the following refactorings:
- Renamed some functions
- Introduced explaining variables
- Cleaned up & added comments
- Used Optional<unsigned> for return value instead of an out parameter
- Added assertions
- Constified a few member functions
No functionality change.
All regressions pass.
