Yes, it is true than an optional end clause is not more useful than
#end comments because Donald's solution does not allow to reliably
recover indentation (except if end clauses are used throughout). Thus,
I agree with Guido that the solution does not add any real value.
Personally, I think that there is no satisfactory solution to all
the problems related to newlines and indentation as long backward
compatibility must be provided. That is why I proposed to depart from
the current syntax.
Donald has done a good job, thank you! For me, it is another piece of
evidence, however, that Python is either left as it is, or another
non-compatible syntax is defined that solves all known problems at
once.
