Re: Show instance for SrcSpan

      Ah, you want to drop constructor field names.  Then I withdraw my
reservations.

thanks for the clarification,
m.

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

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.
