Programs writing backquotes

[Kent M Pitman <KMP@SCRC-STONY-BROOK.ARPA>]

Don't be silly. Programs that write programs to run maybe can generate 
`real' code, but programs that write programs to read better use a 
readable convention. It is not just writing convenience that leads one
to write with backquote. 

Further, the issue of program-manipulation of backquote is not only one
of generation, but of intelligibility of code written by users. It should
be possible to have called vanilla READ and to get backquoted structure
and to be able to identify it as such. The grinder is an obvious example
of a program which needs uo be able to recognize such things, but it would
be easy to conjure others.
