Anonymous type function declaration

Let's have a function:

Func<argsFoo, resultFoo> foo= x=>new resultFoo(x);
Func<argsBar, resultBar> bar= x=>new resultBar(x);
Func<argsBaz, resultBaz> baz= x=>new resultBaz(x);

I want to create a complex function which uses all this functions declared above.

Like this:

Func
<
    Func<argsFoo, resultFoo>,
    Func<argsBar, resultBar>,
    Func<argsBaz,resultBaz>,
    fooBarBazResult
> fooBarBaz=...

The point is such declaration is killing the readability of the programm. Type inference is not working in this case.

Question: can I use something like this?

FooBarBaz<typeof(foo),typeof(bar)>,typeof(baz)>>

I have tried and answer is no. May be anyone has another solution to make shorter the composed function declarations?

You can always declare your own delegate that will be describing your methods:

public delegate resultMy MyDelegate(argsMy arg)

and use the shorter name MyDelegate

Func<FooDelagate, BatDelegate, BazDelegate>

and even that delegate you can name to simplify you code.

Well, you could add a using statement at the top of your file that simplifies that: 

using SomeName = Func<Func<ArgsFoo, ResultFoo>, Func<ArgsBar, ResultBar>, Func<ArgsBaz, ResultBaz>>;

And then you couls just use it as this:

SomeName myFunc = //the func
