RE: [sv-bc] Macro mantis proposals 1397 & 1478

No, I don't agree.  My macro text ended in an escaped identifier.  The
proposal would strip off its trailing whitespace.  In any case, the
example is a natural one for an implementer to think of, so the LRM
really ought to be clear on the point, if only by giving an example.

Brad,

1. It is true that 1339 is formally being revoted. However, there was
informal oral agreement on the last revision of the proposal at the most
recent meeting.

2. Your example probably should not work because of the rule that a
macro text may not begin or end in the middle of a token. The precise
LRM text in 21.5 is

"The text specified for macro text shall not be split across the
following lexical tokens:
- Comments
- Numbers
- String literals
- Identifiers
- Keywords
- Operators" 

Do you agree?

Thanks,
Shalom
