writes the file to disk even if you pass a block

I was surprised to find that the local file is opened and written even if you pass the block. If you’re local working directory isn’t writeable or doesn’t have the space, you’re out of luck.

nope

If you pass nil as local file, it doesn’t write the file and only returns the content as string.
