This issue affects e.g. express used with new route handlers which are required to be non-async in their TS typings. I think in case of variadic arguments, the plugin verifies just the 1st argument and, if it's okay, doesn't even check the rest of the arguments.

• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.
• I haveread the FAQ and my problem is not listed.

Repro

{"rules": {"@typescript-eslint/no-misused-promises":"error",  }}

functionget2(_h1:()=>void,_h2:()=>void){}functionget(..._handlers:Array<()=>void>){}get2(()=>{},async()=>{}// <-- fails, which is what we want);get(()=>{},async()=>{}// <-- this must fail too, but it does not);

Expected Result

Both get() and get2() calls must raise an eslint error.

Actual Result

Only get2() is treated as incorrect, and get() is fine - although it should fail too:
