Add mypy type-checking cell magic to jupyter/ipython.
Save this script to your ipython profile's startup directory.
IPython's directories can be found via `ipython locate [profile]` to find the current ipython directory and ipython profile directory, respectively.
For example, this file could exist on a path like this on mac:
/Users/yourusername/.ipython/profile_default/startup/typecheck.py

Rust…
- is functional
- but not pure, so you can printf-debug without IO() ALL THE FUNCTIONS
- has a strong Hindley-Milner type system
- but has convenient implicit coercions too, so you don't have to cast all over the place
- safe and high-level (with ownership, static/dynamic borrowing, Send and Sync)
- yet deterministic and fast with zero-/low-cost abstractions and RAII
- has a standard build system and dependency management
- but it doesn't force you to use it, and it has a simple Make-like CLI that doesn't hurt
- lets you write your code in the 'modern' IDE of your choice with all bells and whistles

Békésen ülök a Mammut KFC-ben, mellettem két, 24-28 éves forma lány. Egyikük hevesen ecseteli
a pasizás terén véghezvitt hőstetteit.
Sztori #1: Volt egy barátja, annak egy húga. A húgnak volt egy pasija. A csaj ezzel a csávóval jött össze,
még mielőtt a barátjával szakított volna, ezért hetekig titkolóztak – amit a leányzó láthatóan roppant humorosnak tartott.
Sztori #2: Nagyon büszke volt arra is, hogy ezután (meg előtt) volt pár egyéjszakás kalandja is. (vajon közben is voltak…?)
Sztori #3: 2 hónapig volt egy 20 éves (!!!) barátja, aki állítása szerint 16-ként viselkedett. De legalább vicces volt!
Úgy látszik, azt, hogy – idézem "mások előtt is képtelen volt normálisan viselkedni" –, ez teljesen jól ellensúlyozta.
Na, ezek után végre kifújta magát, így hagyta a másik lányt is szóhoz jutni, aki erre: "Jé, ez olyan érdekes! Nekem
