Re: Show instance for SrcSpan

Not at all, just show as e.g. SrcSpan (RealSrcSpan (SrcSpanOneLine "./foo.hs" 4 1 6)) We just avoid showing the srcSpanFile / srcSpanLine / srcSpanSCol / srcSpanECol noise On Mon, Oct 6, 2014 at 3:16 PM, Matthias Fischmann wrote:

Is there any reason I can't put in a diff request to replace the derived Show instance for SrcSpan with a handcrafted one that does not exhausively list the constructors, making it more readable?

I like the notion that `Read . Show` should always work. Dropping parts of a datatype would break that rule.
