```
julia> using JuMP
julia> model = JuMP.Model()
julia> @variable(model, x[1:3])
julia> @variable(model, y[1:3])
julia> @. @constraint(model, x <= y)
```

gives error: `ERROR: At REPL[19]:1: `

@constraint(model, (<=).(x, y))`: Unsupported constraint expression: we don't know how to parse constraints containing expressions of type :..`

`@constraint(model, @. x <= y)`

does not work either, with the following error:

```
ERROR: At REPL[20]:1: `@constraint(model, #= REPL[20]:1 =# @__dot__ x <= y)`: Unsupported constraint expression: we don't know how to parse constraints containing expressions of type :macrocell.
```

I know that we can write `@constraint(model, x .<= y)`

, but the constraint can be much more complex in practice with many dots. Does JuMP support the `@.`

syntax?
