I ran across this sentence in a podcast prepared for English learners:

> 
> She sees such magazines for the garbage that they are, and chooses not to read them.
> 
> 
> 

I can see what it means, but still cannot get my head around how it is structured; **see for** is not a phrasal verb, nor could I find a meaning for **for** that can sit well in the sentence. What is your take on this, please?
