Hungarian Notation

Flags identifiers that use [Systems] Hungarian Notation prefixes.

Reasoning

Systems Hungarian (encoding data types in variable names) stemmed from a misunderstanding of what its inventor meant when they described that prefixes identified the "kind" of variable in a naming scheme dubbed Apps Hungarian. Modern naming conventions in all programming languages heavily discourage the use of Systems Hungarian prefixes.
