Eggs Ackley. The separation of phases valued by some seems to me
just a repeat of Lisp's earlier mistakes with dynamic vs. static
scope, in which code typed at the REPL had different semantics
than code loaded from a file. Also it limits runtime loading and
unloading of syntax, which is valuable in code that reasons about
or interprets code written in multiple other languages.
