The following code is not working for me

float[3] f;
f[] = abs(f)[] * -1.0f;
where abs is a function that returns a float[3];

it complains that f should be attached to some memory.

Is it a bug or am I missing something?

I cannot reproduce the error with the code you've given. It's either missing some import, or a definition of `abs()`. The one in std.math doesn't accept arrays at all.

This is unimplemented currently and no one cares about it.

You can do:

f[] = abs(f)[];
f[] *= -1;
