Haven't thought about it, but this may makes sense, when configuring options in more than one file, e.g. foo.cabal, and stack.yaml, and whichever precedence, should probably be definitive. Likely cumulative behaviour would be more surprising. [ Based on the assumption that GHC options in stack.yaml are in addition to the component-specific options in the cabal file. ] The name is plural, so takes all the options at once. There could be new options to incrementally modify the list of rtsopts: -set-rtsopt? -add-rtsopt? -del-rtsopt? assuming there's a sensible way to accumulate these. -- Viktor.
