I see what you mean, but maybe it can be buffered.

With ae.utils.graphics, even a long chain of operations still 
benefits from pixel being arranged in scanlines. It's like 
"expression templates for images" and maybe we need "expression 
templates for sound".

The memory support for this is often alloca() in the C++ world. 
And it's pretty cumbersome to do everything with buffers.

Indeed wavetable look-up is not stateful.
