 ## FAQ/Caveats
 
-- gore runs code using `go run` for each input. All the inputted lines are
-  evaluated again and again so you can't bind the evaluated time by
-  `time.Now()`, for example. If you don't like this behavior, you may want to use
-  [yaegi](https://github.com/containous/yaegi).
+- gore runs code using `go run` for each input. Every line entered is evaluated
+  repeatedly ([#67](https://github.com/x-motemen/gore/issues/67)),
+  so you can't bind the evaluated time by `time.Now()`, for example.
+  This implementation also makes the execution fairly slow
+  ([#182](https://github.com/x-motemen/gore/issues/182)).
+  This project started from a simple idea to use `go run` for all REPL input.
+  I think this project has provided some value for Go users, but these days
+  there are other REPL implementations that are more actively maintained
+  and run faster. I recommend using [gomacro](https://github.com/cosmos72/gomacro)
+  or [yaegi](https://github.com/containous/yaegi).
 - gore support Go modules. You can load local modules when you start gore at
   the project directory. You don't need to `go get` to check the usage of a
   remote repository, `:import github.com/...` will automatically download that
