Hello!

I do not have a MWE since it is something I have spotted in developing a nested package. What I noticed is that if I have a function such as;

```
function SPHExample.ComputeInteractions!(Position, Kernel, KernelGradient, Density, Velocity, dρdtI, dvdtI, i, j, MotionLimiter, ρ₀, h, h⁻¹, m₀, αD, α, g, c₀, δᵩ, η², H², Cb⁻¹, ν₀, dx, SmagorinskyConstant, BlinConstant, ViscosityTreatment, BoolDDT, OutputKernelValues)
xᵢⱼ² = evaluate(SqEuclidean(), Position[i], Position[j])
if xᵢⱼ² <= H²
xᵢⱼ = Position[i] - Position[j]
dᵢⱼ = sqrt(xᵢⱼ²)
q = clamp(dᵢⱼ * h⁻¹,0.0,2.0)
invd²η² = inv(dᵢⱼ*dᵢⱼ+η²)
∇ᵢWᵢⱼ = @fastpow (αD*5*(q-2)^3*q / (8h*(q*h+η²)) ) * xᵢⱼ
ρᵢ = Density[i]
ρⱼ = Density[j]
vᵢ = Velocity[i]
vⱼ = Velocity[j]
vᵢⱼ = vᵢ - vⱼ
density_symmetric_term = dot(-vᵢⱼ, ∇ᵢWᵢⱼ) # = dot(vᵢⱼ , -∇ᵢWᵢⱼ)
dρdt⁺ = - ρᵢ * (m₀/ρⱼ) * density_symmetric_term
dρdt⁻ = - ρⱼ * (m₀/ρᵢ) * density_symmetric_term
# Do a lot more computations
```

If I define it inside my package then it runs 10x as slow as if I overload it and use it in a new script?

Has anyone experienced something similar and can give some tips?

Kind regards
