I am not too sure but I would say that multiple unrelated expressions are parsed as a block so `(x;y)` is a valid block. You can then replace `(x;y)` by `begin; x; y; end` in the function declaration.

```julia
julia> :((x;y)) |> dump
Expr
  head: Symbol block
  args: Array{Any}((3,))
    1: Symbol x
    2: LineNumberNode
      line: Int64 1
      file: Symbol REPL[1]
    3: Symbol y

```
