Switch from pretty-simple to pretty-show for native output. Update tests. Reason: it turns out that the native output generated by pretty-simple isn't always readable by the native reader. According to https://github.com/cdepillabout/pretty-simple/issues/99 it is not a design goal of the library that the rendered values be readable using 'read'. This makes it unsuitable for our purposes. pretty-show is a bit slower and it uses 4-space indents (non-configurable), but it doesn't have this serious drawback. 2021-09-28 21:17:53 -07:00			`[ Para`
