 The above is a suboptimal solution, however. The feedback we received from the community suggested that many people felt like the `given` keyword was overused, similarly to the `implict` keyword in Scala 2. This overuse is one of the things we'd like to avoid in Scala 3. It leads, for example, to situations like `given (given ...)` which are not nice to read.

+For this release, we have changed the syntax for the contextual parameters. The keyword for the contextual argument group is now `using` instead of `given`. The above snippet now becomes:

 On the call site, the syntax for explicitly specifying the contextual parameters is now:
 
 ```scala
-f(2).with(20)
+f(2)(using 20)

 # Semantics of inline parameters changed
 Inline parameters is a metaprogramming feature of Dotty which allows to splice the body of the parameter on its call site. Previously, inline parameters to methods were required to be known on compile time. With this release, this constraint has been relaxed. The following:
