I am running the following code from the following section in Julia manual: https://docs.julialang.org/en/latest/manual/arrays/#Comprehensions-1:

```
x = rand(8)
[ 0.25*x[i-1] + 0.5*x[i] + 0.25*x[i+1] for i=2:length(x)-1 ]
Float32[ 0.25*x[i-1] + 0.5*x[i] + 0.25*x[i+1] for i=2:length(x)-1 ]
```

all works fine.

Now I define a function:

```
s4() = 0
```

and running the above code fails. More specifically the last expression returns:

```
julia> Float32[ 0.25*x[i-1] + 0.5*x[i] + 0.25*x[i+1] for i=2:length(x)-1 ]
ERROR: invalid redefinition of constant #s4
Stacktrace:
[1] anonymous at .\<missing>:?
```

More specifically the following error happens when:

- function of name
`s1`

,`s2`

,`s3`

or`s4`

is defined; - a type is prepended to the comprehension.

Is it a bug or I am missing someting trivial?
