Title	When rewriting existing functions, do not make a new copy of them with slightly modified code.
Priority	Recommended
Severity level	4
Description	Do not copy-paste an existing function as a local function of your code. Instead, use a wrapper around existing functionality.
Rationale	Multiple forks, duplications and reinventions of the wheel make a code base less modular and less maintainable.
