How to set parallel parameters very easily, where the function needs to use other packages. Using LinearAlgebra as an example, I want to set an isparfor parameter and package it into a function:

At present, if you want to use parallelism, you must set it in the Main main function file like this

```
if isparfor==1 #1 parallel, 0 not parallel
Preformatted textusing Distributed
addprocs(4)
@everywhere using LinearAlgebra
fun1
else
using Linear Algebra
fun1
end
```

I want to make this into a function, but the using must be at the first level, but other parallel processes must use other packages. Is there a good way to pack the parallel parameter using package into a function or module,

so that the call only needs

**funparfor(1) enables parallel**

**funparfor(0) does not enable parallel!**

The desired function is similar to the following

```
using Distributed
function funparfor(isparfor)
if isparfor ==0
addprocs(4)
@everywhere using LinearAlgebra
fun1
else
using Linear Algebra
fun1
end
```
