Or you are doing the sort of things most C code written these days
does. My last C program was taking to an RFID writer over a serial
port to implement ISO 28560 standard library article tags. Bit
fiddling is useful when the storage available on a typical RFID tag is
less than a tweet.

The graphical interface was in Tcl/Tk, because that sort of thing
doesn't leverage the strengths of C. But trying to do the bit fiddling
parts in Tcl would have been the exact opposite of fun.
