* basic stability improvements; refs nimsuggest * fixed dot operator recursive loop & macro suggest * hacky fix for run away dot operator sem check Committing this mostly to make the issue more clear. Perhaps get better feedback. * semExprWithType seems like a better place to check * fixed error messages const case expressions * Clean-up test * stopped the dot operator madness No longer get infinite recursion when seming broken code with a dot operator macro like in jsffi.
