While looking for questions to retag to
operator-precedence, I noticed that operator is currently a synonym of operator-keyword, which is really a tag about operator overloading. This is really confusing, because people tagging their questions operator often meant to use operators.
This has led to the situation where many of the questions in the operator-keyword tag aren't really about any
operator keyword at all, but rather about the use of operators.
Also, after fixing the wrongly tagged operator-keyword questions it would probably not be a bad idea to get rid of the operator-keyword tag altogether. As far as I can see, there is no reason to differentiate it from the operator-overloading tag.
For reference, here are the relevant tag wiki excerpts:
operators (2,328 questions)
Operators are symbols that occur in nearly all programming and coding languages, for performing calculations and comparisons on data.
operator-keyword (735 questions)
In several languages, the operator keyword is used to identify methods which will be used in operator overloading.
operator-overloading (2,313 questions)
Operator overloading is a feature of a programming language that allows custom implementations for operators depending on the types of the operands involved. Some languages allow new operators to be defined while others only allow redefinition of existing ones.
