Base.ComposedFunction{Outer,Inner} <: Function

Represents the composition of two callable objects `outer::Outer` and `inner::Inner`.
Represents the composition of two callable objects `outer::Outer` and `inner::Inner`. That is
```julia
ComposedFunction(outer, inner)(args...; kw...) === outer(inner(args...; kw...))
```
The preferred way to construct instance of `ComposedFunction` is to use the composition operator [`∘`](@ref):
```jldoctest
julia> sin ∘ cos === Base.ComposedFunction(sin, cos)
true
