I am exploring the relationship between a method call, and the particular method chosen. So consider

```
@which randn(Int64, 3, 4, 2)
```

which returns

```
randn(::Type{T}, dims::Integer...) where T in Random at /Users/julia/buildbot/worker/package_macos64/build/usr/share/julia/stdlib/v1.3/Random/src/normal.jl:186
```

First, it would be nice if the link returned corresponded to an existing path on my file system (MacOs 14.x). It does not. Not sure how that is possible.

Second, let us actually call the function:

```
randn(Int64, 3,4, 2)
```

I get the error below.

```

Given the error, why does the function

```
randn(::Type{T}, dims::Integer...) where T
```

exist? Doesn’t the three dot operator signify an arbitrary number of integers? If the function call only works for two integers, why not create a specialized type to that effect.The only answer I have is that the function accepts one or two integers as arguments, and the … was the easy way to accomplish this.
