----
-
-By and large, the possible indentation regions coincide with those regions where braces `{...}` are also legal, no matter whether the braces enclose an expression or a set of definitions. There is one exception, though: Arguments to function can be enclosed in braces but they cannot be simply indented instead. Making indentation always significant for function arguments would be too restrictive and fragile.
-
-To allow such arguments to be written without braces, a variant of the indentation scheme is implemented under language import
-```scala
-import language.experimental.fewerBraces
-```
-Alternatively, it can be enabled with command line option `-language:experimental.fewerBraces`.
-
-This variant is more contentious and less stable than the rest of the significant indentation scheme. It allows to replace a function argument in braces by a `:` at the end of a line and indented code, similar to the convention for class bodies. It also allows to leave out braces around arguments that are multi-line function values.
-
-## Using `:` At End Of Line
-
-
-Similar to what is done for classes and objects, a `:` that follows a function reference at the end of a line means braces can be omitted for function arguments. Example:
-```scala
-times(10):
-  println("ah")
-  println("ha")
-```
-
-The colon can also follow an infix operator:
-
-```scala
-credentials ++ :
-  val file = Path.userHome / ".credentials"
-  if file.exists
-  then Seq(Credentials(file))
-  else Seq()
-```
-
-Function calls that take multiple argument lists can also be handled this way:
-
-```scala
-val firstLine = files.get(fileName).fold:
-    val fileNames = files.values
-    s"""no file named $fileName found among
-      |${values.mkString(\n)}""".stripMargin
-  :
-    f =>
-      val lines = f.iterator.map(_.readLine)
-      lines.mkString("\n)
-```
-
-
-## Lambda Arguments Without Braces
-
-Braces can also be omitted around multiple line function value arguments:
-```scala
-val xs = elems.map x =>
-  val y = x - 1
-  y * y
-xs.foldLeft (x, y) =>
-  x + y
-```
-Braces can be omitted if the lambda starts with a parameter list and `=>` or `=>?` at the end of one line and it has an indented body on the following lines.
-
-## Syntax Changes
-
-```
-SimpleExpr       ::=  ...
-                   |  SimpleExpr `:` IndentedArgument
-                   |  SimpleExpr FunParams (‘=>’ | ‘?=>’) IndentedArgument
-InfixExpr        ::=  ...
-                   |  InfixExpr id `:` IndentedArgument
-IndentedArgument ::=  indent (CaseClauses | Block) outdent
-```
-
-Note that a lambda argument must have the `=>` at the end of a line for braces
-to be optional. For instance, the following would also be incorrect:
-
-```scala
-  xs.map x => x + 1   // error: braces or parentheses are required
-```
-The lambda has to be enclosed in braces or parentheses:
-```scala
-  xs.map(x => x + 1)  // ok
-```
