Scala - mutable (var) method parameter reference

Question

EDIT: I keep getting upvotes here. Just for the record, I no longer think this is important. I haven\'t needed it since I posted it.

I would like to do following in

Here's a couple of suggestions:

1) Update your function a bit

def save(srcPath: String, destPath: String) {
  var dp = destPath
  if (!dp.endsWith('/'))
    dp+= '/'
  // do something, but with dp instead of destPath
}

2) Create a utility function to use before calling save

def savedPath(path: String) = 
  if(path.endsWith("/")) 
    path
  else
    path + "/"

//call your save method on some path
val myDestPath = ...
val srcPath = ...
save(srcPath, savedPath(myDestPath))
