- 모나드Monads 이해하기 https://economiceco.tistory.com/18187
- Haskell for Imperative Programmers #17 - Monads https://youtu.be/IBB7JpbClo8
- 13분 35초
-
A monad is an algebraic structure in category theory, and in Haskell it is used to describe computations as sequences of steps, and to handle side effects such as state and IO.
-
Monads are abstract, and they have many useful concrete instances.
-
Monads provide a way to structure a program.
-
They can be used (along with abstract data types) to allow actions (e.g. mutable variables) to be implemented safely.
https://www.futurelearn.com/info/courses/functional-programming-haskell/0/steps/27246
-
https://en.wikipedia.org/wiki/Monoid
- In abstract algebra, a branch of mathematics, a monoid is a set equipped with an associative binary operation and an identity element. For example, the nonnegative integers with addition form a monoid, the identity element being 0.
-
Monadic lenses are the optic for right monad modules III

If you want to use package hiding and options, then you can try one
of the following:
* If you want to start a different project configuration
than /Users/globalyoung/.stack/global-project/stack.yaml, then you can use
stack init to create a new stack.yaml for the packages in the
current directory.
* If you want to use the project configuration
at /Users/globalyoung/.stack/global-project/stack.yaml, then you can add to its 'packages' field.

But before you doom yourself, here are some things you should know:
-
Don't forget to run 'doom sync', then restart Emacs, after modifying ~/.doom.d/init.el or ~/.doom.d/packages.el.
This command ensures needed packages are installed, orphaned packages are removed, and your autoloads/cache files are up to date. When in doubt, run 'doom sync'!
-
If something goes wrong, run
doom doctor. It diagnoses common issues with your environment and setup, and may offer clues about what is wrong. -
Use 'doom upgrade' to update Doom. Doing it any other way will require additional steps. Run 'doom help upgrade' to understand those extra steps.
-
Access Doom's documentation from within Emacs via 'SPC h d h' or 'C-h d h' (or 'M-x doom/help')
Have fun!
