1. F# refactoring
possibilities
BASIC REFACTORINGS THAT I WOULD LIKE TO HAVE IN VISUAL STUDIO IDE

2. Purge tuples

Which is cleaner? It depends.

This is just a matter of clean code.

Also needed: Rename a variable/function/parameter

3. Move discriminated union to subtype

Usually coder starts with the first one…

But the data (string*int) is so much easier to access in the later one!

Even later, it may not be clear that what sub-types belongs to where in the type
hierarchy

4. Convert to immutable

Usually you need either all or just one property to be changed to
immutable/mutable

5. Pattern match to If-else

Usually in case of booleans (or when-patterns)

Back-conversion not possible, if left-hand-side compare condition is not the same

6. Move function parameters

7. Move List, Seq or Array conversion
in composition

8. Extract Function-Composition

9. Extract to active pattern

Longer code but sometimes better visibility of business logic intentions.

10. Convert to Option-module

Option-module (bind, map, etc.) could be used more…

One step more would be List-module to recursion, or recursion to fold

11. Strip un-used computation
expression wrapping

Just minor cleanup if Async (or other monads) are not really used to bind any
data to computation

12. Basic object-oriented features

Generate a base class (and move some methods to there)

Create and/or Implement interface

So that user doesn’t have to remember interface-syntax

13. Simple pattern/snippet to make a
simple MailboxProcessor

So that user doesn’t have to remember the whole syntax

Or a way to convert existing list/dictionary to a MailboxProcessor…
