It's undoubtedly aimed at musical audio generation and signal processing. A quick search will reveal the number of gotchas in implementing even a simple alias-free (bandlimited interpolation) digital sawtooth wave, never mind arbitrary wave tables. The rebirth of analog audio synths was partially driven by the complex behaviors of real analog circuitry - particularly when you account for saturation, hysteresis and other "imperfections" that don't occur naturally in a digital simulation.
