Hello,

I am wondering whether there is a nice way of passing arguments to a function that is itself an argument to a function. So, currently, I have a piece of code that looks like this:

```julia
function func_manip(func)
    # Uses the function in some way
end

function linear_func(x, a)
    return x*a
end

for i in 0:10
    f(x) = linear_func(x, i)
    func_manip(f)
end

```

My guts tells me that this is not the most elegant way of doing this. I was thinking that maybe there would be a way of doing something where instead of defining the `f` function, I could simply specify which arguments I pass with the inputted function in `func_manip`. So something like:

```julia
function func_manip(func)
    # Uses the function in some way
end

function linear_func(x, a)
    return x*a
end

for i in 0:10
    func_manip(f(::, i))
end

```

Otherwise, I thought about adding another argument to the `func_manip` that I would be plugging into `func` inside `func_manip`, but for the precise application I was working on, it was making the code a bit crowded. Maybe there is another method that essentially does the same thing.  
Any help is appreciated!

An anonymous function works very nicely in this case:

```julia
julia> function func_manip(func)
           @show func(1)
       end
func_manip (generic function with 1 method)

julia> function linear_func(x, a)
           return x*a
       end
linear_func (generic function with 1 method)

julia> for i in 0:10
           func_manip(x -> linear_func(x, i))
       end

```

where `x -> linear_func(x, i)` creates a new function of one variable and _closes over_ the variable `i` (a.k.a a _closure_).

I like that! Thanks!
