ghc with incorrect arguments deletes source file

I'm just learning haskell and I mistakenly passed the -o argument to ghc instead of -c. When combined with the -i argument (which I also mistakenly supplied, thinking of ghci), this unlinks the file named by -o.

This is certainly a case of PEBKAC, but ghc should probably do something other than unlinking the file.

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.0.3
$ ls path/to/
source.hs
$ ghc -i . -o path/to/source.hs 
/usr/bin/ld: cannot find .: File format not recognized
collect2: ld returned 1 exit status
$ ls path/to/
$
