[plt-scheme] Re: [redex] Alternative to named holes

They were removed because all of the (non-trivial) uses of them we
know of were broken, in the sense that any language that used them
also had the property that they triggered the "zero/multiple holes"
error, for some expression in the language. Also, all of those uses
could be rewritten to fix the error but also to remove the use if
multiple holes.

If you're not sure how to rewrite out the named holes, send me
something and I can probably help.
