When the variable name is the description that should be in the comments.
Idea: Comments that automattically populate the end of any line a given variable is invoked on, including spelling out formulas from that line. ie: float y=mx+b // (cartesian y value)=(slope)(cartesian x value)+(cartisian y-intercept)
“Duplicated” coments not actually in the file, but specified witt the creation of such variables and spread around by the code editor /IDE.
