So I think this use of array-ref should be inlined.

Same for other simple functions such as e.g.

scheme@(guile-user)> ,optimize (real-part 1+1i)
$1 = (real-part 1.0+1.0i)
scheme@(guile-user)> 

imag-part, magnitude, and so on.

If you would like to make a precise list, that would be helpful.

Cheers,

At least everything from §6.6.2.7 to §6.6.2.13 in http://www.gnu.org/software/guile/manual/html_node/

I've noticed that a few of these are already reduced, it seems quite random. For example everything in §6.6.2.8 is reduced, then logand is reduced but logior is not.
