Bitwise operators are a lot more useful when doing system level programming in Assembler, C ,etc.

Around the early 90's when I was writing 3D texture mapped engines designed for 386/386sx+ systems (16 Megahertz!), I used them constantly. You can use bitshifts and bitlogic to do quick (and dirty) multiplies/divides by powers of 2, cheap modulus operations, collision detection, etc. Under those constraints, every clock cycle counts. At that time, you had to roll your own video drivers which meant screwing around with SVGA registers (all bit-masking)and all other arcane kind of things.

That said, if you are doing system level programming you will probably use them quite often.

To be honest, I haven't ever had the need (yet) to use them in any Perl applications.
