Re: Formal spec; implementation; nesting
Regarding the nesting rule: Perhaps it should be an error to write two
#; tokens in a row? It's not something humans are likely to do, and
since the syntax is for human convenience (not for macros) it's not
something likely to come up in a macro transformer. That permits at
least three implementations:
1. Signal an error.
2. Use the "logical" rule favored by current implementations.
3. Use the "intuitive" rule favored by Paul and I.
