> `1:5 .+ 0.5` is such a dangerous pattern

Linking [this related post](https://discourse.julialang.org/t/unitrange-in-1-7-rc1-bug/68327), where one danger is illustrated by:

```julia
v = (1:5) .- 1/7
length(v) == 4 # true  

v = collect(1:5) .- 1/7
length(v) == 5 # true  

```

_ **NB:** using Julia 1.7_
