I’m using Julia v0.6.0 and my old codes with √(x) where x is a Vector is giving warning as

```
julia> √(x)
WARNING: sqrt{T <: Number}(x::AbstractArray{T}) is deprecated, use sqrt.(x) instead.
Stacktrace:

```

As expeceted, `sqrt.(x)`

works without warning.

However using dot with squareroot symbol raises error

```
julia> √.(x)
ERROR: syntax: invalid identifier name "."
```

How can I use `√`

over a vector with new version of julia?
