Using the "register" storage class feels really alien for C code written in 2025…
It has a slightly different meaning now, instead of hinting to the compiler that the variable should be placed in a register it now means that it is illegal to take the address of the variable (e.g. cannot create a pointer from it):

Might be useful in some situations although I currently can't think of any :)
