rc's lexer and grammar treated = as a special
symbol - just like ( or | or & or ; - and so it couldn't
be used as a literal except when quoted.
That is, "foo x=y" was a syntax error, not an equivalent to "x=y
foo".
OK, distinction noted. It was a long time ago.
One of the tidyings I did during covid lockdown was to
rewrite
rc's parser not to use yacc anymore [1], specifically to make
it easy to allow "foo x=y". As I wrote in the commit message,
dd fans rejoice! (Also fans of -foo=bar flag syntax.)
Very cool. Have other Plan 9 distros picked this up? Just wondering.
Thanks,
