What if we required a trailing comma for that case?

```julia
julia> (1; x=2)
2

julia> (1,; x=2)
ERROR: syntax: unexpected semicolon in tuple around REPL[24]:1
Stacktrace:
 [1] top-level scope
   @ REPL[24]:1

```

Not much different from disambiguating `(1)` from `(1,)` for making either an expression or `Tuple`.
