I was wondering if it would be a good idea to create a tag for control-flow-graph.
Firstly, it is a popular data structure used in a number of areas of computer science, especially compilers and software engineering.
Secondly, people use "cfg" to abbreviate control flow graph resulting in an ambiguity with "context free grammars" which has its own tag cfg. I recently came across a question that used the cfg tag but was really talking about control flow graphs. Now there is a tag for control-flow, but perhaps that might not be as intuitive as "cfg"?
