So I've decided to give it a try.
Open installation instructions and went thru "easy install with uvx" / "get and run our sgell script" until get "pip install ty".
I do not want use other tools so I started it in pet project directory as "ty check". Is shows me progressbar and "98/99 files" then hang.
I restarted it and it hung on "68/99" and started using 100% of cpu core. I waited for 15 min and killed it.
Try to get more information about current file but there is no verbose mode but colorful "ty --help" output.
Lets wait for a year then try again.
Edit: +"then try again"
