As the compiler tells you, the line

     alias x0 = Remove(indicies[i] - i, Args);

doesn't parse.

You can't assign the result of a function call to an `alias`.
If `Remove` is indeed a function, you need to use `enum` instead 
of `alias`.
If `Remove` is a template, you're missing an exclamation mark.

You also have a typo: "indicies" should be "indices".
